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This model is unpublished and is provided as a stable numerical framework on which a more physical model may be built.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 -0.33; sigmak 1.0; sigmaEps 1.3; alphaInversion 0.7; }
