Application
    compressibleInterFilmFoam

Description
    Solver for 2 compressible, non-isothermal immiscible fluids using a VOF
    (volume of fluid) phase-fraction based interface capturing approach
    and surface film modelling.

    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.
