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 hollowcylinder- flare and a Mach 6.8 flow over a hyperboloidflare 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
