interPhaseChangeDyMFoam
Description
Solver for 2 incompressible, isothermal immiscible fluids with phase-change
(e.g. cavitation). Uses a VOF (volume of fluid) phase-fraction based
interface capturing approach, with optional mesh motion and mesh topology
changes including adaptive re-meshing.
The momentum and other fluid properties are of the "mixture" and a
single momentum equation is solved.
The set of phase-change models provided are designed to simulate cavitation
but other mechanisms of phase-change are supported within this solver
framework.
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
