Detailed Description

template<class BasicTurbulenceModel>
class Foam::LESModels::dynamicKEqn< BasicTurbulenceModel >

Dynamic one equation eddy-viscosity model.

Eddy viscosity SGS model using a modeled balance equation to simulate the behaviour of k in which a dynamic procedure is applied to evaluate the coefficients.

Reference: 

    Kim, W and Menon, S. (1995).
    A new dynamic one-equation subgrid-scale model for
    large eddy simulation.
    In 33rd Aerospace Sciences Meeting and Exhibit, Reno, NV, 1995.

There are no default model coefficients but the filter used for KK must be supplied, e.g. 

    dynamicKEqnCoeffs
    {
        filter simple;
    }
