Detailed Description

Apply Prandtl mixing-length based damping function to the specified geometric delta to improve near-wall behavior or LES models.

    delta = min(geometricDelta, (kappa/Cdelta)*y)

Example specification in the turbulenceProperties dictionary:

delta           Prandtl;

PrandtlCoeffs
{
    delta   cubeRootVol;

    cubeRootVolCoeffs
    {
        deltaCoeff      1;
    }

    // Default coefficients
    kappa           0.41;
    Cdelta          0.158;
}
