Detailed Description

template<class BasicMomentumTransportModel>
class Foam::RASModels::continuousGasKEpsilon< BasicMomentumTransportModel >

k-epsilon model for the gas-phase in a two-phase system supporting phase-inversion.

In the limit that the gas-phase fraction approaches zero a contribution from the other phase is blended into the k and epsilon equations up to the phase-fraction of alphaInversion at which point phase-inversion is considered to have occurred and the model reverts to the pure single-phase form.

This model is unpublished and is provided as a stable numerical framework on which a more physical model may be built.

The default model coefficients are

    continuousGasKEpsilonCoeffs
    {
        Cmu             0.09;
        C1              1.44;
        C2              1.92;
        C3              0;
        sigmak          1.0;
        sigmaEps        1.3;
        alphaInversion  0.7;
