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 Sparlat and Allmaras one-equation model and the Jacon and Knight, Menter and Rumsey, and Gibson and Dafa’Alla 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 Menter and Rumsey turbulence model in its BSL variant.

Keywords
