•A Brief Reminder of SIMPLE Algorithm
•Extension of SIMPLE algorithm to:
•Solution of two-Phase flow in Convergent-Divergent Nozzle
use pressure-correction equation continuity constraint
use staggered gridderivation of the pressure
equation
Conservation Equations can be cast in the following general form:
The above equation can be discretized using the Finite-Volume method:
Geometric conservation equation
1D, two-phase flow:Equations:2 Continuity + 2 Momentum-x + 1 Geom. Cons.
Variables:V1, V2, P, r1, r2
Conservation Equations can be cast in the following general form:
The above equation can be discretized using the Finite-Volume method:
