Abstract: The capability of the lag model for shock-induced separated flows in supersonic nozzles was discussed. The Reynold-averaged Navier-Stokes equations and the baseline Wilcox k-ω turbulence model were used to predict the equilibrium eddy viscosity. It was found that the lag model introduced history effect and relaxation of the eddy viscosity over the equilibrium values predicted by the baseline model. Analysis shows that the inclusion of the lag model significantly improves the results where there is strong shock-induced separation.
