Abstract

The Spalart and Allmaras turbulence model has been implemented in a finite volume code using an implicit finite difference technique. A wide range of turbulent flows have been computed to validate the implementation and numerical results are shown. A special attention is paid to hypersonic applications. A hypersonic wind tunnel flow, a Mach 5 flow over a hollow-cylinder-flare and a Mach 6.8 flow over a hyperboloid-flare have been considered. The critical comparison between the numerical results and experimental data has given useful elements to evaluate the model behaviour in high speed flow modeling.
