Contrib/CompressibleMixingPhaseChangeFoam
From OpenFOAMWiki
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 :
By converting to volume fluxes we get:
Using equation of state, we can reformulate substantial derivative for density in terms of pressure for any phase:
Failed to parse (unknown function "\p"): \frac {d \rho}{dt}= \frac {d \hat \rho} {dt} + \psi \frac {dp} {dt} + \p \frac {d \psi}{d t}
* Phase change model * Momentum equation * Energy equation
