PREDICTION OF SEPARATED FLOWS WITH A NEW BACKFLOW TURBULENCE MODEL

A recently introduced backflow turbulence model for separated flows has been used to calculate the reattaching flow over a backward facing step and the shock-induced separation over an axisymmetric bump. Results are compared with experimental data and with calculations using the k-e turbulence model and the JohnsonKing model. It is concluded that the new backflow turbulence model performs as well as the Johnson-King model and better than the k-e model.
