The aim of this study is to simulate unsteady, three-dimensional supersonic flow past an open rectangular cavity to better understand the flow physics and three-dimensional nature of the cavity flow oscillations. The simulations are performed for the flow at a free stream Mach number of 1.5. The compressible time-dependent Reynolds-Averaged Navier-Stokes equations in three dimensions are solved using the GASPex software employing the k - ω turbulence model and Roe scheme for the numerical fluxes. The results of the computations are compared with the experimental results in terms of overall acoustic sound pressure levels within the cavity. The unsteady and three-dimensional nature of the flow is emphasized in the study. Computational results are presented for the unsteady shock and vortex structures utilizing pressure contours, numerical schlieren images, vorticity and streamlines for flow visualization.
