Description
    Solver for two compressible, non-isothermal immiscible fluids using a VOF
    (volume of fluid) phase-fraction based interface capturing approach.
 
    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.
