Thermal Performance Predictions

Input for Thermal Analysis Lexan 10 mm twin wall MWS with Nanogel

Lexan 16 mm triple wall MWS with Nanogel



Lexan 40 mm Thermoclick MWS with Nanogel

Thermal conductivity of the Nanogel -12 mW/m-K

Density of the Nanogel 70 kg/m3

Specific heat of the Nanogel - Approx. 1 KJ/kg-K

Emissivity of the Nanogel ~ >0.9

Analysis Details & Assumptions

ABAQUS® 6.9. Standard and CAE are used for Pre, Post processing and Analysis. The calculation is carried out using a 2D heat transfer analysis conforming to EN ISO 10211-1:1995(E) It is assumed that principle heat flow in the section is perpendicular to a plane parallel to the external and internal surfaces. It is assumed that the emissivity of the surfaces adjoining the air cavities is 0.9 (ISO 10077-2:2003(E)) Solid continuum (DC2D4 & DC2D3) element is used The following typical properties of Lexan* Polycarbonate is used. The air gap thermal conductivity are predicted as per ISO (ISO 10077-2:2003(E)

Problem Formulation

The U-value was predicted as per ISO 10211 . The air cavity thermal properties was predicted as per ISO 10077-2. For Nanogel the Lexan* MWS cavity thermal property was replaced with Nanogel thermal properties. Internal and external heat transfer coefficients for U value prediction are as per ISO 10077-2:2003 (E)/ EN 673 External heat transfer coefficient, he = 25 W/m2K Internal heat transfer coefficient, hi = 7.7 W/m2K Both the standard Lexan MWS and Nanogel filled Lexan MWS results are reported.
