Detailed Description

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

Additional buoyancy generation/dissipation term applied to the k and epsilon equations of the standard k-epsilon model.

Reference:

    Henkes, R.A.W.M., Van Der Vlugt, F.F. & Hoogendoorn, C.J. (1991).
    Natural Convection Flow in a Square Cavity Calculated with
    Low-Reynolds-Number Turbulence Models.
    Int. J. Heat Mass Transfer, 34, 1543-1557.

This implementation is based on the density rather than temperature gradient extending the applicability to systems in which the density gradient may be generated by variation of composition rather than temperature. Further, the 1/Prt coefficient is replaced by Cg to provide more general control of model.

The default model coefficients are

    buoyantKEpsilonCoeffs
    {
        Cg              1.0;
    }
