Standard k-epsilon turbulence model with additional source terms corresponding to PDR basic drag model (basic.H)
The default model coefficients correspond to the following:
PDRkEpsilonCoeffs { Cmu 0.09; C1 1.44; C2 1.92; C3 -0.33; // only for compressible C4 0.1; sigmak 1.0; // only for compressible sigmaEps 1.3; Prt 1.0; // only for compressible }
The turbulence source term appears in the equation for the generation of turbulence due to interaction with unresolved obstacles.
In the equation is added as a source term.
