Abstract: Abstract Direct numerical simulations (DNS) of compressible supersonic channel flow of air at Reynolds numbers ranging from Re τ = 180 to Re τ = 560 and Mach numbers ranging from M = 0.3 to M = 3.0 have been performed. A Navier-Stokes solver of high order accuracy has been vectorized and parallelized to run efficiently on the Hitachi SR8000-F1. Budgets of the Reynolds stresses and the passive scalar fluxes are presented, as well as explanations concerning the reduction of the pressure-correlation terms, using a Green's function approach.
