Direct Numerical Simulations of High Speed Flow Over Cavity

Abstract

Direct numerical simulations are used to investigate the effect of Mach number on the unsteady flow of an open cavity. The implicit solution is obtained for the compressible Navier-Stokes Equations using compact sixth-order spatial differencing coupled with tenth-order implicit filters. Results for transonic and subsonic flow over a two dimensional cavity are presented for the sound pressure level and pressure fluctuation frequencies.
