Transport Equations
Where
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.
