Hi, does anybody know the difference between incompressible k-epsilon model and compressible k-epsilon model in OpenFOAM? I found that the compressible model has more model constants. For example, the model constants for the incompressible RNG k-epsilon model are
RNGkEpsilonCoeffs
{
Cmu 0.0845;
C1 1.42;
C2 1.68;
sigmak 0.71942;
sigmaEps 0.71942;
eta0 4.38;
beta 0.012;
}
howerer, the model constants for the compressible RNG k-epsilon model are
RNGkEpsilonCoeffs
{
Cmu 0.0845;
C1 1.42;
C2 1.68;
C3 -0.33; // only for compressible
Prt 1.0; // only for compressible
sigmak 0.71942;
sigmaEps 0.71942;
eta0 4.38;
beta 0.012;
}
By the way, where can I find some references about the details of turbulence models in OpenFOAM?
