The zeta-f model is a robust modification of the elliptic relaxation model. For the incompressible Newtonian fluid the final set of equations constituting the model is given below.
Turbulent kinetic energy
Turbulent kinetic energy dissipation rate
Normalized velocity scale
Elliptic relaxation function
Production of the turbulent kinetic energy
Modulus of the mean rate-of-strain tensor
