Detailed Description

template<class BasicTurbulenceModel>
class Foam::RASModels::kEpsilonLopesdaCosta< BasicTurbulenceModel >

Variant of the standard k-epsilon turbulence model with additional source terms to handle the changes in turbulence in porous regions represented by the powerLawLopesdaCosta porosity model.

Reference:

    Costa, J. C. P. L. D. (2007).
    Atmospheric flow over forested and non-forested complex terrain.

The default model coefficients are

    kEpsilonLopesdaCostaCoeffs
    {
        Cmu         0.09;
        C1          1.44;
        C2          1.92;
        sigmak      1.0;
        sigmaEps    1.3;
    }
