Detailed Description

template<class BasicTurbulenceModel>
class Foam::LESModels::continuousGasKEqn< BasicTurbulenceModel >

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This model is unpublished and is provided as a stable numerical framework on which a more physical model may be built.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

    continuousKEqnCoeffs
    {
        Ck              0.094;
        Ce              1.048;
        alphaInversion  0.7;
    }
