The zeta-f model is a robust modification of the elliptic relaxation model. The set of equations, for the incompressible Newtonian fluid, constituting the model is given below.
Turbulent kinetic energy
Turbulent kinetic energy dissipation rate
The normalized fluctuating velocity normal to the streamlines
The elliptic relaxation function
The production of the turbulent kinetic energy
The modulus of the mean rate-of-strain tensor
The turbulence time scale
The turbulence length scale
