Class
    Foam::multiphaseMixture

Description
    Incompressible multi-phase mixture with built in solution for the
    phase fractions with interface compression for interface-capturing.

    Derived from transportModel so that it can be unsed in conjunction with
    the incompressible turbulence models.

    Surface tension and contact-angle is handled for the interface
    between each phase-pair.
