Turbulent Production

The turbulent production term is defined identically to the corresponding term in the standard k-e model (see Eqn. 189).

Buoyancy Production

The production term is defined identically to the corresponding term in the standard k-e model (see Eqn. 193).

Compressibility Modification

The dilatation dissipation is defined identically to the corresponding term in the standard k-e model (see Eqn. 197).

Relation for Turbulent Viscosity

The turbulent viscosity is computed as:
