Class
    Foam::ThermalPhaseChangePhaseSystem

Description
    Class to provide interfacial heat and mass transfer between a number of
    phases according the interfacial temperature approximated by the saturation
    temperature.

    Based on the implemnetaion described in:

    \verbatim
        Peltola, J., Pättikangas, T., Bainbridge, W., Lehnigk, R., Schlegel, F.
        (2019).
        On Development and validation of subcooled nucleate boiling models for
        OpenFOAM Foundation Release.
        NURETH-18 Conference Proceedings, Portland, Oregon, United States, 2019.
    \endverbatim

    The present implementation includes simplified support for non-volatile
    components in addition to a single volatile component in order to account
    compressibility effects when non-volatile gas bubbles of non-volatile gas
    filled pressure reservoirs are present.

    The phase change mass transfer calculation is still only dependent on the
    interfacial temperature estimate and interfacial heat transfer models.
    The mass diffusion effects in presence of non-volatile components at the
    interface are neglected.
