We develop a model for turbulent eddy viscosity as a solution of a quartic equation. The model is consistent with the renormalization group (RNG)-based low-Reynolds number approximation for turbulent viscosity. The model has been tested for flow over a backward facing step and the predicted results show very good agreement with the experimental data.
