Assessment of Several Turbulence Models Applied to Supersonic Flows in Three-Dimensions – Part III

摘要

In the present work, the Van Leer and the Liou and Steffen Jr. flux vector splitting schemes are implemented to solve the three-dimensional Favre-averaged Navier-Stokes equations. The Sparlat and Allmaras one-equation model, and the Menter and Rumsey and the 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 blunt body. The results have demonstrated that the Van Leer scheme using the Menter and Rumsey turbulence model in its SST variant has yielded the best value of the stagnation pressure and is the most efficient scheme.
