Class
    Foam::TwoResistanceHeatTransferPhaseSystem

Description
    Class which models interfacial heat transfer between a number of phases.
    Two heat transfer models are stored at each interface, one for each phase.
    This permits definition of an interface temperature with which heat transfer
    occurs. It also allows derived systems to define other thermodynamic
    properties at the interface and therefore represent phase changes.
