Detailed Description

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 $ G_{R} $ appears in the $ \kappa-\epsilon $ equation for the generation of turbulence due to interaction with unresolved obstacles.

In the $ \epsilon $ equation $ C_{1} G_{R} $ is added as a source term.

In the $ \kappa $ equation $ G_{R} $ is added as a source term.
