Application
    reactingTwoPhaseEulerFoam

Description
    Solver for a system of 2 compressible fluid phases with a common pressure,
    but otherwise separate properties. The type of phase model is run time
    selectable and can optionally represent multiple species and in-phase
    reactions. The phase system is also run time selectable and can optionally
    represent different types of momentun, heat and mass transfer.
