Solver for two fluids with phase change (for example - water <---> steam), pressure and temperature density dependence
Model Equations
=== Equation of state === === Liquid volume transport ===
Let us consider transport of liquid (heavy phase) volume fraction :
* Phase change model * Momentum equation * Energy equation
