Realisable k-epsilon model
In these equations, represents the generation of turbulence kinetic energy due to the mean velocity gradients, calculated in same manner as standard k-epsilon model. is the generation of turbulence kinetic energy due to buoyancy, calculated in same way as standard k-epsilon model.
Modelling Turbulent Viscosity
where is the mean rate-of-rotation tensor viewed in a rotating reference frame with the angular velocity . The model constants and are given by:
