Partially Averaged Navier–Stokes Simulations of High Speed Mixing Environment

Abstract

Accurate simulation of the fuelair mixing environment is crucial for highfidelity scramjet calculations. We compute the velocity fields of jet into supersonic freestream flow and cavity flow typical of scramjet flameholding applications at different scale resolutions using the partiallyaveraged Navier–Stokes (PANS) method. We present a sequence of variable resolution computations to demonstrate the potential of PANS method for highspeed mixing environment calculations.
