Abstract: Numerical simulation of essentially unsteady regimes of a supersonic viscous compressible gas flow over a 3D cavity with the aid of explicit kinetically consistent finite difference schemes was carried out using different multiprocessor computer systems. The principal features of the flow structure and properties of pressure oscillations at critical body points were studied.
