27 Description
28  Solver for 2 incompressible, isothermal immiscible fluids using a VOF
29  (volume of fluid) phase-fraction based interface capturing approach.
30 
31  The momentum and other fluid properties are of the "mixture" and a single
32  momentum equation is solved.
33 
34  Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
35 
36  For a two-fluid approach see twoPhaseEulerFoam.
