This paper aims to study the influence of heat transfer on thin film flow of a reactive third order fluid with variable viscosityand slip boundary condition The problem is formulated in the form of coupled nonlinear equations governing the flow togetherwith appropriate boundary conditions Approximate analytical solutions for velocity and temperature are obtained using AdomianDecomposition Method (ADM) Such solutions are also obtained by using Optimal Homotopy Asymptotic Method (OHAM) andare compared with ADM solutions Both of these solutions are found identical as shown in graphs and tables The graphical resultsfor embedded flow parameters are also shown
1 Introduction
Thin film fluid flows exist in various aspects of daily life Inengineering we see their usage in condensers distillationunits and heat exchangers In geophysical events we see thinfluid films in the forms of drillingmud heat pipes and debrisflow In biological sciences we can see thin fluid films coatingthe airways in the lungs and thin tear films covering theeye These are a few examples of common use of thin fluidfilms All these occurrences can be modeled using mathe-matical principles The material properties such as viscosityand density change accordingly when a fluid is subjectedto a temperature change This phenomenon mostly occursin heat exchangers chemical reactors or processes wherecomponents are cooled
Properties of isothermal flows (viscosity at constant tem-perature) are important in many situations There have alsobeen many studies done on variety of nonisothermal (tem-perature dependent viscosity) flows of fluids particularlyGoussis andKelly [1 2] andHwang andWeng [3] investigatedthe stability of a fluid film with variable viscosity flowing
down a heated plan while Reisfeld and Bankoff [4] and Wuand Hwang [5] independently considered the progressionand final substrate of a fluid film with variable viscosity on aheated horizontal substrate subjected to surface tension andvan derWaals forces Sansom et al [6] considered the scatter-ing of a thin film flow with temperature dependent viscosityon a horizontal substrate for different viscosity models forboth heated and cooled substrate without internal heatingwithin the film and for a substrate at the ambient temperaturewith constant internal heating within the film
Many researchers have contributed relevant work in thisfield Amongst them Khaled et al [7] studied heat transferinside thin film flow with variable pressure whereas Nadeemand Awais [8] investigated the thin film unsteady flow withvariable viscosityThe freemicropolar convection for the caseof a symmetric boundary conditions or asymmetric heatingwas investigated by Chamkha et al [9] later on proceededby Saleh et al [10] Few other relevant studies may be foundin [11 12] and the references therein One of the well-knownmodels amongst non-Newtonian fluids for thin film is a thirdgrade fluid which has its constitutive equations based on

strong theoretical foundations where the relation betweenstress and strain is nonlinear Therefore in the present workwe have chosen third grade fluid to study its thin film flowover a vertical belt
On the other hand several numerical and approximatemethods are used by many authors to study real worldproblems appearing in mathematics fluid mechanics andengineering sciences Few of these methods include Keller-box [13] shooting [14] Homotopy Perturbation Method(HPM) [15] Homotopy Analysis Method (HAM) and Opti-mal Homotopy Asymptotic Method (OHAM) [16 17] Appli-cations of OHAM for solving nonlinear equations arising inheat transfer have been investigated byMarinca andHerisanu[18] Marinca et al [19] analysed steady flow of a fourth gradefluid past a porous plate using OHAM Micropolar flow in aporous channel with highmass transfer has been investigatedby Joneidi [20] These methods deal with the nonlinearproblems effectively The work under various configurationson the thin film flows has been discussed by Siddiqui et al[21] In [22] Siddiqui et al examined the thin film flows ofSisko and Oldroyd-6 constant fluids on a moving belt Usingthe same idea Gul et al [23 24] investigated MHD thin filmflow of a third grade fluid for lifting and drainage problemsConstant and variable viscosity fluid has been used in allthese studies In [24] they studied variable viscosity with no-slip boundary conditions However in the present problemwe have chosen Reynolds model (exponential expression)which is based on variable viscosity in the presence of slipboundary conditions More exactly we have shown the effectof variable viscosity with heat transfer in a thin film fluid flowsuch as silicate melts and polymers past a lubricating beltIn these fluids viscous friction generates a local increase intemperature near the belt with a resultant viscosity decreaseand frequent rise of the flow velocity This velocity increasemay produce an additional growth of the local temperaturediscussed by Costa et al [25] Analytical solution for MHDflow in a third grade fluid with variable viscosity has beendiscussed by Ellahi and Riaz [26] Approximate analyticalsolution for flow of a third grade fluid through a parallel platechannel filled with a porousmedium has been investigated byAksoy et al [27]
Based on the above motivation the present paper aimsto study the effect of heat on viscosity into a thin film flowof a third grade fluid over a vertical belt with slip boundaryconditions using ADM and OHAM In 1992 Adomian [2829] introduced the ADM for the approximate solutionsfor linear and nonlinear problems Wazwaz [30 31] usedADM for reliable treatment of Bratu-type and Emden-Fowlerequations Alam et al investigated the thin film flow ofJohnson-Segalman fluids for lifting and drainage problems[32]

3 Formulation of the Lift Problem
Consider a wide flat belt moves vertically upward at constantspeed 119881 through a large bath of a third grade liquid Thebelt carries with it a layer of liquid of constant thickness120575 Cartesian coordinate system is chosen for analysis inwhich the 119910-axis is taken parallel to the belt and 119909-axis isperpendicular to the belt Assume that the flow is steadyand laminar after a small distance above the liquid surfacelayer while external pressure is atmospheric everywhere Thegeometry of the problems is shown in Figures 1(a) and 1(b)
Velocity and temperature fields are
v = (0 V (119909) 0)
Θ = Θ (119909)
(7)
Modeled slip boundary conditions are
v = 119881 minus 120574119879119909119910 Θ = Θ0 at 119909 = 0
119889v119889119909
= 0 Θ = Θ1 at 119909 = 120575(8)
Inserting the velocity field from (7) in continuity equation (1)and in Cauchy stress equation (4) the continuity equation (1)satisfies identically while (4) gives the components of stresstensor as
119879119910119910 = minus119875 + (21205721 + 1205722) (119889v119889119909

5 Formulation of Drainage Problem
The geometry and assumptions of the problem are the sameas in previous problem Consider a film of non-Newtonianliquid draining at volume flow rate 119876 down the vertical beltThe belt is stationary and the fluid drains down the belt dueto gravity The gravity in this case is opposite to the previouscase Therefore the stock number is positively mentioned in(14)The coordinate system is selected the same as in previouscase Assume the flow is steady and laminar while externalpressure is neglected Consider fluid shear forces keep thegravity balanced and the film thickness remains constant

6 Solution of Drainage Problem
61 The ADM Solution By making use of ADM in (14)and (15) the Adomian polynomials in (24)ndash(27) for bothproblems are the sameThe different velocity components areobtained as follows
Components of ProblemThe boundary conditions of first andsecond components for drainage velocity profile are the sameas given in (37) The boundary conditions for temperaturedistribution are also the same as given in (38) but the solutionof these components is different dependent on the differentvelocity profile of drainage and lift problemsThe terms V2(119909)and Θ2(119909) are too large to be written above therefore theirexpression is mentioned graphically

only for comparison The comparison of analytical methodsADMandOHAMof the presentwork for lift velocity andheattransfer analysis is shown in Figures 2(a) and 2(b) Figures3(a) and 3(b) show the comparison of ADM and OHAM fordrainage velocity and temperature distribution Effect of theBrinkman number 119861119903 for lift velocity profile has been shownin Figure 4(a) Behavior of the lift velocity field V can be seenwhen the velocity of fluid is maximum at the surface of thebelt while it is minimum at the surface of the fluid It hasbeen found out that the velocity of the fluid decreases for largevalue of119861119903 as compared to small values of119861119903The observationof Brinkman number 119861119903 associated with heat in lift problemhas been countered in Figure 4(b) Since 119861119903 is related withthe viscous dissipation term in energy equation higher valuesof the 119861119903 should essentially lead to an increase in amount of
heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning
effect Increase in 120573 results in decreasing temperature distri-bution as shown in Figure 8(b) The drain velocity increaseswith increase in Brinkman number as shown in Figure 9(a)Figure 9(b) specifies the effect of 119861119903 for drain temperaturedistribution The temperature distribution increases as the119861119903 increases and becomes more trampled for higher valueof 119861119903 In Figure 10(a) the effect of stock number 119878119905 hasbeen shown for drainage flow It can be seen that there is apoint near the belt where the velocity of the fluid becomesapproximately the same for different values of stock number119878119905 because friction of the belt becomes negligible at thispoint On increasing the stock number 119878119905 after this pointthe curvature of velocity increases due to negligible frictionThe effect of stock number 119878119905 on temperature distribution

On the other hand several numerical and approximatemethods are used by many authors to study real worldproblems appearing in mathematics fluid mechanics andengineering sciences Few of these methods include Keller-box [13] shooting [14] Homotopy Perturbation Method(HPM) [15] Homotopy Analysis Method (HAM) and Opti-mal Homotopy Asymptotic Method (OHAM) [16 17] Appli-cations of OHAM for solving nonlinear equations arising inheat transfer have been investigated byMarinca andHerisanu[18] Marinca et al [19] analysed steady flow of a fourth gradefluid past a porous plate using OHAM Micropolar flow in aporous channel with highmass transfer has been investigatedby Joneidi [20] These methods deal with the nonlinearproblems effectively The work under various configurationson the thin film flows has been discussed by Siddiqui et al[21] In [22] Siddiqui et al examined the thin film flows ofSisko and Oldroyd-6 constant fluids on a moving belt Usingthe same idea Gul et al [23 24] investigated MHD thin filmflow of a third grade fluid for lifting and drainage problemsConstant and variable viscosity fluid has been used in allthese studies In [24] they studied variable viscosity with no-slip boundary conditions However in the present problemwe have chosen Reynolds model (exponential expression)which is based on variable viscosity in the presence of slipboundary conditions More exactly we have shown the effectof variable viscosity with heat transfer in a thin film fluid flowsuch as silicate melts and polymers past a lubricating beltIn these fluids viscous friction generates a local increase intemperature near the belt with a resultant viscosity decreaseand frequent rise of the flow velocity This velocity increasemay produce an additional growth of the local temperaturediscussed by Costa et al [25] Analytical solution for MHDflow in a third grade fluid with variable viscosity has beendiscussed by Ellahi and Riaz [26] Approximate analyticalsolution for flow of a third grade fluid through a parallel platechannel filled with a porousmedium has been investigated byAksoy et al [27]
Based on the above motivation the present paper aimsto study the effect of heat on viscosity into a thin film flowof a third grade fluid over a vertical belt with slip boundaryconditions using ADM and OHAM In 1992 Adomian [2829] introduced the ADM for the approximate solutionsfor linear and nonlinear problems Wazwaz [30 31] usedADM for reliable treatment of Bratu-type and Emden-Fowlerequations Alam et al investigated the thin film flow ofJohnson-Segalman fluids for lifting and drainage problems[32]

Cauchy stress tensor T is given by
T = minus119901I + S (4)

3 Formulation of the Lift Problem
Consider a wide flat belt moves vertically upward at constantspeed 119881 through a large bath of a third grade liquid Thebelt carries with it a layer of liquid of constant thickness120575 Cartesian coordinate system is chosen for analysis inwhich the 119910-axis is taken parallel to the belt and 119909-axis isperpendicular to the belt Assume that the flow is steadyand laminar after a small distance above the liquid surfacelayer while external pressure is atmospheric everywhere Thegeometry of the problems is shown in Figures 1(a) and 1(b)
Velocity and temperature fields are
v = (0 V (119909) 0)
Θ = Θ (119909)
(7)
Modeled slip boundary conditions are
v = 119881 minus 120574119879119909119910 Θ = Θ0 at 119909 = 0
119889v119889119909
= 0 Θ = Θ1 at 119909 = 120575(8)
Inserting the velocity field from (7) in continuity equation (1)and in Cauchy stress equation (4) the continuity equation (1)satisfies identically while (4) gives the components of stresstensor as
119879119910119910 = minus119875 + (21205721 + 1205722) (119889v119889119909

For Reynoldrsquos model the dimensionless viscosity is

5 Formulation of Drainage Problem
The geometry and assumptions of the problem are the sameas in previous problem Consider a film of non-Newtonianliquid draining at volume flow rate 119876 down the vertical beltThe belt is stationary and the fluid drains down the belt dueto gravity The gravity in this case is opposite to the previouscase Therefore the stock number is positively mentioned in(14)The coordinate system is selected the same as in previouscase Assume the flow is steady and laminar while externalpressure is neglected Consider fluid shear forces keep thegravity balanced and the film thickness remains constant

Components of ProblemThe boundary conditions of first andsecond components for drainage velocity profile are the sameas given in (37) The boundary conditions for temperaturedistribution are also the same as given in (38) but the solutionof these components is different dependent on the differentvelocity profile of drainage and lift problemsThe terms V2(119909)and Θ2(119909) are too large to be written above therefore theirexpression is mentioned graphically

heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions

5 Formulation of Drainage Problem
The geometry and assumptions of the problem are the sameas in previous problem Consider a film of non-Newtonianliquid draining at volume flow rate 119876 down the vertical beltThe belt is stationary and the fluid drains down the belt dueto gravity The gravity in this case is opposite to the previouscase Therefore the stock number is positively mentioned in(14)The coordinate system is selected the same as in previouscase Assume the flow is steady and laminar while externalpressure is neglected Consider fluid shear forces keep thegravity balanced and the film thickness remains constant

heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning
effect Increase in 120573 results in decreasing temperature distri-bution as shown in Figure 8(b) The drain velocity increaseswith increase in Brinkman number as shown in Figure 9(a)Figure 9(b) specifies the effect of 119861119903 for drain temperaturedistribution The temperature distribution increases as the119861119903 increases and becomes more trampled for higher valueof 119861119903 In Figure 10(a) the effect of stock number 119878119905 hasbeen shown for drainage flow It can be seen that there is apoint near the belt where the velocity of the fluid becomesapproximately the same for different values of stock number119878119905 because friction of the belt becomes negligible at thispoint On increasing the stock number 119878119905 after this pointthe curvature of velocity increases due to negligible frictionThe effect of stock number 119878119905 on temperature distribution

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions

5 Formulation of Drainage Problem
The geometry and assumptions of the problem are the sameas in previous problem Consider a film of non-Newtonianliquid draining at volume flow rate 119876 down the vertical beltThe belt is stationary and the fluid drains down the belt dueto gravity The gravity in this case is opposite to the previouscase Therefore the stock number is positively mentioned in(14)The coordinate system is selected the same as in previouscase Assume the flow is steady and laminar while externalpressure is neglected Consider fluid shear forces keep thegravity balanced and the film thickness remains constant

6 Solution of Drainage Problem
61 The ADM Solution By making use of ADM in (14)and (15) the Adomian polynomials in (24)ndash(27) for bothproblems are the sameThe different velocity components areobtained as follows
Components of ProblemThe boundary conditions of first andsecond components for drainage velocity profile are the sameas given in (37) The boundary conditions for temperaturedistribution are also the same as given in (38) but the solutionof these components is different dependent on the differentvelocity profile of drainage and lift problemsThe terms V2(119909)and Θ2(119909) are too large to be written above therefore theirexpression is mentioned graphically

only for comparison The comparison of analytical methodsADMandOHAMof the presentwork for lift velocity andheattransfer analysis is shown in Figures 2(a) and 2(b) Figures3(a) and 3(b) show the comparison of ADM and OHAM fordrainage velocity and temperature distribution Effect of theBrinkman number 119861119903 for lift velocity profile has been shownin Figure 4(a) Behavior of the lift velocity field V can be seenwhen the velocity of fluid is maximum at the surface of thebelt while it is minimum at the surface of the fluid It hasbeen found out that the velocity of the fluid decreases for largevalue of119861119903 as compared to small values of119861119903The observationof Brinkman number 119861119903 associated with heat in lift problemhas been countered in Figure 4(b) Since 119861119903 is related withthe viscous dissipation term in energy equation higher valuesof the 119861119903 should essentially lead to an increase in amount of
heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning
effect Increase in 120573 results in decreasing temperature distri-bution as shown in Figure 8(b) The drain velocity increaseswith increase in Brinkman number as shown in Figure 9(a)Figure 9(b) specifies the effect of 119861119903 for drain temperaturedistribution The temperature distribution increases as the119861119903 increases and becomes more trampled for higher valueof 119861119903 In Figure 10(a) the effect of stock number 119878119905 hasbeen shown for drainage flow It can be seen that there is apoint near the belt where the velocity of the fluid becomesapproximately the same for different values of stock number119878119905 because friction of the belt becomes negligible at thispoint On increasing the stock number 119878119905 after this pointthe curvature of velocity increases due to negligible frictionThe effect of stock number 119878119905 on temperature distribution

5 Formulation of Drainage Problem
The geometry and assumptions of the problem are the sameas in previous problem Consider a film of non-Newtonianliquid draining at volume flow rate 119876 down the vertical beltThe belt is stationary and the fluid drains down the belt dueto gravity The gravity in this case is opposite to the previouscase Therefore the stock number is positively mentioned in(14)The coordinate system is selected the same as in previouscase Assume the flow is steady and laminar while externalpressure is neglected Consider fluid shear forces keep thegravity balanced and the film thickness remains constant

6 Solution of Drainage Problem
61 The ADM Solution By making use of ADM in (14)and (15) the Adomian polynomials in (24)ndash(27) for bothproblems are the sameThe different velocity components areobtained as follows
Components of ProblemThe boundary conditions of first andsecond components for drainage velocity profile are the sameas given in (37) The boundary conditions for temperaturedistribution are also the same as given in (38) but the solutionof these components is different dependent on the differentvelocity profile of drainage and lift problemsThe terms V2(119909)and Θ2(119909) are too large to be written above therefore theirexpression is mentioned graphically
Inserting slip boundary conditions from (45) and from(18) and (19) in (29)ndash(34) the different components solutionis obtained as

only for comparison The comparison of analytical methodsADMandOHAMof the presentwork for lift velocity andheattransfer analysis is shown in Figures 2(a) and 2(b) Figures3(a) and 3(b) show the comparison of ADM and OHAM fordrainage velocity and temperature distribution Effect of theBrinkman number 119861119903 for lift velocity profile has been shownin Figure 4(a) Behavior of the lift velocity field V can be seenwhen the velocity of fluid is maximum at the surface of thebelt while it is minimum at the surface of the fluid It hasbeen found out that the velocity of the fluid decreases for largevalue of119861119903 as compared to small values of119861119903The observationof Brinkman number 119861119903 associated with heat in lift problemhas been countered in Figure 4(b) Since 119861119903 is related withthe viscous dissipation term in energy equation higher valuesof the 119861119903 should essentially lead to an increase in amount of
heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning
effect Increase in 120573 results in decreasing temperature distri-bution as shown in Figure 8(b) The drain velocity increaseswith increase in Brinkman number as shown in Figure 9(a)Figure 9(b) specifies the effect of 119861119903 for drain temperaturedistribution The temperature distribution increases as the119861119903 increases and becomes more trampled for higher valueof 119861119903 In Figure 10(a) the effect of stock number 119878119905 hasbeen shown for drainage flow It can be seen that there is apoint near the belt where the velocity of the fluid becomesapproximately the same for different values of stock number119878119905 because friction of the belt becomes negligible at thispoint On increasing the stock number 119878119905 after this pointthe curvature of velocity increases due to negligible frictionThe effect of stock number 119878119905 on temperature distribution

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions

5 Formulation of Drainage Problem
The geometry and assumptions of the problem are the sameas in previous problem Consider a film of non-Newtonianliquid draining at volume flow rate 119876 down the vertical beltThe belt is stationary and the fluid drains down the belt dueto gravity The gravity in this case is opposite to the previouscase Therefore the stock number is positively mentioned in(14)The coordinate system is selected the same as in previouscase Assume the flow is steady and laminar while externalpressure is neglected Consider fluid shear forces keep thegravity balanced and the film thickness remains constant

6 Solution of Drainage Problem
61 The ADM Solution By making use of ADM in (14)and (15) the Adomian polynomials in (24)ndash(27) for bothproblems are the sameThe different velocity components areobtained as follows
Components of ProblemThe boundary conditions of first andsecond components for drainage velocity profile are the sameas given in (37) The boundary conditions for temperaturedistribution are also the same as given in (38) but the solutionof these components is different dependent on the differentvelocity profile of drainage and lift problemsThe terms V2(119909)and Θ2(119909) are too large to be written above therefore theirexpression is mentioned graphically

only for comparison The comparison of analytical methodsADMandOHAMof the presentwork for lift velocity andheattransfer analysis is shown in Figures 2(a) and 2(b) Figures3(a) and 3(b) show the comparison of ADM and OHAM fordrainage velocity and temperature distribution Effect of theBrinkman number 119861119903 for lift velocity profile has been shownin Figure 4(a) Behavior of the lift velocity field V can be seenwhen the velocity of fluid is maximum at the surface of thebelt while it is minimum at the surface of the fluid It hasbeen found out that the velocity of the fluid decreases for largevalue of119861119903 as compared to small values of119861119903The observationof Brinkman number 119861119903 associated with heat in lift problemhas been countered in Figure 4(b) Since 119861119903 is related withthe viscous dissipation term in energy equation higher valuesof the 119861119903 should essentially lead to an increase in amount of
heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions

5 Formulation of Drainage Problem
The geometry and assumptions of the problem are the sameas in previous problem Consider a film of non-Newtonianliquid draining at volume flow rate 119876 down the vertical beltThe belt is stationary and the fluid drains down the belt dueto gravity The gravity in this case is opposite to the previouscase Therefore the stock number is positively mentioned in(14)The coordinate system is selected the same as in previouscase Assume the flow is steady and laminar while externalpressure is neglected Consider fluid shear forces keep thegravity balanced and the film thickness remains constant

6 Solution of Drainage Problem
61 The ADM Solution By making use of ADM in (14)and (15) the Adomian polynomials in (24)ndash(27) for bothproblems are the sameThe different velocity components areobtained as follows
Components of ProblemThe boundary conditions of first andsecond components for drainage velocity profile are the sameas given in (37) The boundary conditions for temperaturedistribution are also the same as given in (38) but the solutionof these components is different dependent on the differentvelocity profile of drainage and lift problemsThe terms V2(119909)and Θ2(119909) are too large to be written above therefore theirexpression is mentioned graphically

only for comparison The comparison of analytical methodsADMandOHAMof the presentwork for lift velocity andheattransfer analysis is shown in Figures 2(a) and 2(b) Figures3(a) and 3(b) show the comparison of ADM and OHAM fordrainage velocity and temperature distribution Effect of theBrinkman number 119861119903 for lift velocity profile has been shownin Figure 4(a) Behavior of the lift velocity field V can be seenwhen the velocity of fluid is maximum at the surface of thebelt while it is minimum at the surface of the fluid It hasbeen found out that the velocity of the fluid decreases for largevalue of119861119903 as compared to small values of119861119903The observationof Brinkman number 119861119903 associated with heat in lift problemhas been countered in Figure 4(b) Since 119861119903 is related withthe viscous dissipation term in energy equation higher valuesof the 119861119903 should essentially lead to an increase in amount of
heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning
effect Increase in 120573 results in decreasing temperature distri-bution as shown in Figure 8(b) The drain velocity increaseswith increase in Brinkman number as shown in Figure 9(a)Figure 9(b) specifies the effect of 119861119903 for drain temperaturedistribution The temperature distribution increases as the119861119903 increases and becomes more trampled for higher valueof 119861119903 In Figure 10(a) the effect of stock number 119878119905 hasbeen shown for drainage flow It can be seen that there is apoint near the belt where the velocity of the fluid becomesapproximately the same for different values of stock number119878119905 because friction of the belt becomes negligible at thispoint On increasing the stock number 119878119905 after this pointthe curvature of velocity increases due to negligible frictionThe effect of stock number 119878119905 on temperature distribution

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions

For heat the boundary conditions are identical as given in(36) (38) and (40) regarding both the problems
6 Solution of Drainage Problem
61 The ADM Solution By making use of ADM in (14)and (15) the Adomian polynomials in (24)ndash(27) for bothproblems are the sameThe different velocity components areobtained as follows
Components of ProblemThe boundary conditions of first andsecond components for drainage velocity profile are the sameas given in (37) The boundary conditions for temperaturedistribution are also the same as given in (38) but the solutionof these components is different dependent on the differentvelocity profile of drainage and lift problemsThe terms V2(119909)and Θ2(119909) are too large to be written above therefore theirexpression is mentioned graphically
Inserting slip boundary conditions from (45) and from(18) and (19) in (29)ndash(34) the different components solutionis obtained as

only for comparison The comparison of analytical methodsADMandOHAMof the presentwork for lift velocity andheattransfer analysis is shown in Figures 2(a) and 2(b) Figures3(a) and 3(b) show the comparison of ADM and OHAM fordrainage velocity and temperature distribution Effect of theBrinkman number 119861119903 for lift velocity profile has been shownin Figure 4(a) Behavior of the lift velocity field V can be seenwhen the velocity of fluid is maximum at the surface of thebelt while it is minimum at the surface of the fluid It hasbeen found out that the velocity of the fluid decreases for largevalue of119861119903 as compared to small values of119861119903The observationof Brinkman number 119861119903 associated with heat in lift problemhas been countered in Figure 4(b) Since 119861119903 is related withthe viscous dissipation term in energy equation higher valuesof the 119861119903 should essentially lead to an increase in amount of
heat being generated by the shear forces in the fluid leadingto increase in the fluid temperature
In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning
effect Increase in 120573 results in decreasing temperature distri-bution as shown in Figure 8(b) The drain velocity increaseswith increase in Brinkman number as shown in Figure 9(a)Figure 9(b) specifies the effect of 119861119903 for drain temperaturedistribution The temperature distribution increases as the119861119903 increases and becomes more trampled for higher valueof 119861119903 In Figure 10(a) the effect of stock number 119878119905 hasbeen shown for drainage flow It can be seen that there is apoint near the belt where the velocity of the fluid becomesapproximately the same for different values of stock number119878119905 because friction of the belt becomes negligible at thispoint On increasing the stock number 119878119905 after this pointthe curvature of velocity increases due to negligible frictionThe effect of stock number 119878119905 on temperature distribution

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions

In Figure 5(a) we observed that the velocity decreaseswith an increase in the stock number 119878119905 due to friction forcethe effect of stock number seems to be smaller near the beltIt can be seen that there is a point in the domain wherethe velocity of the fluid becomes approximately identicalfor different values of stock number 119878119905 The reason is thatthe friction of the belt becomes negligible at this pointOn increasing stock number 119878119905 after this point in liftingflow the velocity decreases due to negligible friction Theeffect of stock number 119878119905 on temperature distribution hasbeen illustrated in Figure 5(b) It has been observed thatthe temperature Θ increases steadily by increasing 119878119905 InFigure 6 it has been noticed that the speed of the fluid near

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile
For small values of 120573 the velocity profile differs littlefrom theNewtonian oneHowever when120573 is increased theseprofiles become more flatten showing the shear thinning

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions

the belt is greater than the speed at the surface When weincrease the slip parameter then due to decrease in frictionforce the velocity of the fluid decreases gradually towardsthe surface of the belt The effect of viscosity parameter 119872on lift velocity V has been shown in Figure 7(a) The speedof flow decreases with increasing119872 It can also be seen thatthe thickness of thin film increases in case of dilatant fluidsand decreases in pseudoplastic fluids In Figure 7(b) increasein viscosity parameter 119872 results in increasing temperaturedistribution steadily Figure 8(a) indicates the influence ofnon-Newtonian effect 120573 on lift velocity profile

drainage of fluid Problems have been solved analyticallyby using Adomian Decomposition Method (ADM) Thecomparison of ADM and Optimal Homotopy AsymptoticMethod (OHAM) has been derived graphically and numer-ically Expression for velocity fields and temperature dis-tribution has been presented and sketched These solutionsare valid not only for small but also for large values ofemerging parameters The observation of Brinkman number119861119903 associated with heat is countered in both lift and drainageproblems Since119861119903 is relatedwith the viscous dissipation termin heat equation higher values of the 119861119903 should essentiallylead to an increase in the amount of heat being generated bythe shear forces in the fluid leading to increase in the fluidtemperature It has been observed that the temperature Θ
increases monotonically on increasing 119878119905 The speed of flowdecreases with increasing viscosity parameter119872 Increase in119872 increases the temperature distribution It can also be seenthat the thickness of thin film increases in case of dilatantfluids and decreases in pseudoplastic fluids According to thebest of our knowledge no research has been carried out yetregarding our study This is our first attempt to handle thisproblemwith variable viscosity and slip boundary conditions
