This investigation deals with the modification of streamline curvature effects in the k ‐ε turbulence model for the case of recirculating flows. Based upon an idea that the modification of curvature effects in C 2 should not be made in regions where the streamline curvature is small, a hybrid k ‐ε model extended from the modification originally proposed by Srinivasan and Mongia is developed. A satisfactory agreement of model predictions with experimental data reveals that the hybrid k ‐ε model can perform better simulation of recirculating turbulent flows.
