Detailed Description

template<class TurbulenceThermophysicalTransportModel>
class Foam::turbulenceThermophysicalTransportModels::nonUnityLewisEddyDiffusivity< TurbulenceThermophysicalTransportModel >

Non-unity-Lewis-Eddy-diffusivity based temperature gradient heat flux model for RAS or LES of turbulent flow. Allows independent specification of turbulent Prandtl and Schmidt numbers. Unity laminar Lewis number is assumed.

The heat flux source is implemented as an implicit energy correction to the temperature gradient based flux source. At convergence the energy correction is 0.

Usage

LES
{
    model           nonUnityLewisEddyDiffusivity;
    Prt             0.85;
    Sct             0.7;
}
