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 Zhou, Davidson and Olsson, Kergaravat and Knight, Yoder, Georgiadids and Orkwis, Coakley, and Rumsey, Gatski, Ying and Bertelrud two-equation models are used in order to close the problem. The physical problem under study is the supersonic flow around a simplified version of the VLS (Brazilian “Satellite Launcher Vehice”) configuration. The results have demonstrated that the stagnation pressure ahead of the VLS configuration is better predicted by the Kergaravat and Knight turbulence model in its Launder and Spalding variant.
