26 
27 Description
28  Standard k-epsilon turbulence model with additional source terms
29  corresponding to PDR basic drag model (\link basic.H \endlink)
30 
31  The default model coefficients correspond to the following:
32  @verbatim
33  PDRkEpsilonCoeffs
34  {
35  Cmu 0.09;
36  C1 1.44;
37  C2 1.92;
38  C3 -0.33; // only for compressible
39  C4 0.1;
40  sigmak 1.0; // only for compressible
41  sigmaEps 1.3;
42  Prt 1.0; // only for compressible
43  }
44  @endverbatim
45 
46  The turbulence source term \f$ G_{R} \f$ appears in the
47  \f$ \kappa-\epsilon \f$ equation for the generation of turbulence due to
48  interaction with unresolved obstacles.
49 
50  In the \f$ \epsilon \f$ equation \f$ C_{1} G_{R} \f$ is added as a source
51  term.
52 
53  In the \f$ \kappa \f$ equation \f$ G_{R} \f$ is added as a source term.
