Foam::solvers::twoPhaseVoFSolver
|
|
|
|
Description
|
|
Solver module base-class for 2 immiscible fluids using 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.
|
|
|
|
Either mixture or two-phase transport modelling may be selected. In the
|
|
mixture approach a single laminar, RAS or LES model is selected to model the
|
|
momentum stress. In the Euler-Euler two-phase approach separate laminar,
|
|
RAS or LES selected models are selected for each of the phases.
|
|
|
|
Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
|
|
pseudo-transient and steady simulations.
|
|
|
|
Optional fvModels and fvConstraints are provided to enhance the simulation
|
|
in many ways including adding various sources, Lagrangian
|
|
particles, surface film etc. and constraining or limiting the solution.
