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 Wilcox and Rubesin, Wilcox, Jacon and Knight, and Zhou, Davidson and Olsson two-equation models are used in order to close the problem. The physical problem under study is the “cold gas” hypersonic flow around a reentry capsule configuration. The results have demonstrated that the aerodynamic coefficient of lift is better predicted by the Wilcox and Rubesin turbulence model; However, the stagnation pressure ahead of the reentry capsule configuration is better predicted by the Wilcox turbulence model.
