NUMERICAL SIMULATION OF FLOW IN THE WAKE REGION AT SUPERSONIC SPEEDS

Abstract

The paper presents results of a numerical simulation of supersonic flow
around cones and sphere – cylinder – flare configurations in the framework of
the Reynolds averaged Navier – Stokes equations. Space flow fields of supersonic
flow around cones and sphere – cylinder – flare configurations are presented.
Qualitative features of the supersonic flow around the considered configurations
associated with the development of the recirculating zone, the region of attachment,
the flow in the wake region, and the region of recompression with the formation
of the shock wave are considered. Simulation results are compared with
the experimental data on flow visualization. A comparison between the calculation
results of the base pressure and the base drag coefficients and the experiment
results is presented.
