Class
    Foam::incompressibleInterPhaseTransportModel

Description
    Transport model selection class for the interFoam family of solvers.

    By default the standard mixture transport modelling approach is used in
    which a single momentum stress model (laminar, non-Newtonian, LES or RAS) is
    constructed for the mixture.  However if the \c simulationType in
    constant/momentumTransport is set to \c twoPhaseTransport the alternative
    Euler-Euler two-phase transport modelling approach is used in which separate
    stress models (laminar, non-Newtonian, LES or RAS) are instantiated for each
    of the two phases allowing for different modeling for the phases.
