Description
|
|
Solver for 2 compressible, isothermal 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. Turbulence modelling is generic,
|
|
i.e. laminar, RAS or LES may be selected.
