The default model coefficients are
twophasekOmegaCoeffs
{
Cmu 0.09;
alphaOmega 0.52;
betaOmega 0.072;
C3om 0.35;
C4om 1.0;
KE2 1.0;
KE4 1.0;
alphaKomega 0.5;
alphaOmegaOmega 0.5;
Clim 0.0;
sigmad 0.0
popeCorrection false;
}
For the revisited version of the model from Wilcox (2006), model coefficients should be modified following:
twophasekOmegaCoeffs
{
betaOmega 0.0708;
alphaKomega 0.6;
Clim 0.875;
sigmad 0.125
popeCorrection True (only for 3D cases);
}
