Abstract

In the present work, the Van Leer flux vector splitting scheme is implemented to solve the two-dimensional Favre-averaged Navier-Stokes equations. The Baldwin and Lomax, Wilcox, Menter and Rumsey, and Kergaravat and Knight turbulence models are used in order to close the problem. The physical problem under study is the supersonic flow along a ramp. The results have demonstrated that the Kergaravat and Knight model in its Launder and Spalding variant captured the boundary layer detachment with consequent detection of circulation bubble formation. The shock angle is better predicted by the Kergaravat and Knight model in its Launder and Spalding variant.
