Abstract

Detached eddy simulation (DES) is an effective numerical simulation method for unsteady separated flow since it combines the advantages of both Reynolds averaged Navier-Stokes (RANS) and large eddy simulation (LES) methods. Spalart-Allmaras (SA) based DES method is used for the re-entry case under hypersonic condition. Comparison of the pressure and heat flux distributions shows that the numerical results agree well with the experiment data and thus validate the advantages of the DES method. Compressibility corrections were added in the original SA turbulent model. In the hypersonic flow characterization, the introduction of compressibility corrections can better the original turbulent method's simulation capability.
