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This model is unpublished and is provided as a stable numerical framework on which a more physical model may be built.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