Detailed Description

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

The k-epsilon-phit-f turbulence closure model for incompressible and compressible flows.

The model is a three-transport-equation linear-eddy-viscosity turbulence closure model alongside an elliptic relaxation equation.


Input fields

k : Turbulent kinetic energy [m2/s2]
epsilon : Turbulent kinetic energy dissipation rate [m2/s3]
phit : Normalised wall-normal fluctuating velocity scale [-]
f : Elliptic relaxation factor [1/s]

The default model coefficients are (LUU:Eqs. 19-20): 

        kEpsilonPhitFCoeffs
        {
            includeNu   true;    // include nu in (LUU: Eq. 17), see Notes
            Cmu         0.22;    // Turbulent viscosity constant
            Ceps1a      1.4;     // Model constant for epsilon
            Ceps1b      1.0;     // Model constant for epsilon
            Ceps1c      0.05;    // Model constant for epsilon
            Ceps2       1.9;     // Model constant for epsilon
            Cf1         1.4;     // Model constant for f
            Cf2         0.3;     // Model constant for f
            CL          0.25;    // Model constant for L
            Ceta        110.0;   // Model constant for L
            CT          6.0;     // Model constant for T
            sigmaK      1.0;     // Turbulent Prandtl number for k
            sigmaEps    1.3;     // Turbulent Prandtl number for epsilon
            sigmaPhit   1.0;     // Turbulent Prandtl number for phit = sigmaK
        }
Note
The name of the original variable replacing 'v2' is 'phi' (LUU:Eq. 14). However, the name 'phi' preexisted in OpenFOAM; therefore, this name was replaced by 'phit' herein.

Including nu in DphitEff even though it is not present in (LUU:Eq. 17) provided higher level of resemblance to benchmarks for the tests considered, particularly for the peak skin friction (yet, pressure-related predictions were unaffected). Users can switch off nu in DphitEff by using includeNu entry in kEpsilonPhitFCoeffs as shown above in order to follow the reference paper thereat. includeNu is left true by default. See GitLab issue #1560.
