Difference of definition between HEM and VOF models
Dear Foam USers,
I am trying to make simulation of cavitation in nozzle and confused about the differences between HEM and VOF models which are used in cavitatingFOAM and InterPhaseChangeFoam. When i look at the definitions of the solvers: HTML Code:
1. [B]interPhaseChangeFoam[/B]: (incompressible) VOF+ Transport equation of vapor fraction→ source terms for vaporization and condensation Also when i look at the original Schneer HTML Code:
[Schnerr G, Sauer J. Physical and numerical modeling of unsteady cavitation dynamics. Fourth International Conference on Multiphase Flow, New Orleans, USA2001.] HTML Code:
[Yuan W, Schnerr GH. Optimization of Two-Phase Flow in Injection Nozzles: Interaction of Cavitation and External Jet Formation. ASME; 2002.] and in another paper above explanation is called homogeneous mixtured model.: HTML Code:
Kunz RF, Boger DA, Stinebring DR, Chyczewski TS, Lindau JW, Gibeling HJ, et al. A preconditioned Navier–Stokes method for two-phase flows with application to cavitation prediction. Computers & Fluids. 2000;29:849-75. If i am wrong please someone can correct me... Thanks in advance... |
Hi shipman,
In my limited experience on this topic:
