Class
Foam::compressible::RASModels::PDRkEpsilon
Description
Standard k-epsilon turbulence model with additional source terms
corresponding to PDR basic drag model (\link basic.H \endlink)
The default model coefficients correspond to the following:
@verbatim
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
}
@endverbatim
The turbulence source term \f$ G_{R} \f$ appears in the
\f$ \kappa-\epsilon \f$ equation for the generation of turbulence due to
interaction with unresolved obstacles.
In the \f$ \epsilon \f$ equation \f$ C_{1} G_{R} \f$ is added as a source
term.
In the \f$ \kappa \f$ equation \f$ G_{R} \f$ is added as a source term.
