Abstract

RANS computations of the supersonic flow around a cylinder fixed between parallel plates are described. The free-stream Mach number is M = 1.85. Test results concerning the influence exerted by the mesh resolution and turbulence model on the predicted structure of the viscous-inviscid interaction are obtained. Parametric computations are carried out for several relative distances between the plates. Three-dimensional effects resulting from the interaction of boundary layers with the leading edge of the cylinder are investigated. It is shown that the flow structure changes qualitatively with a decrease in the distance between the plates. Specifically, an additional detached shock is formed, the length and height of the separation region increase, and the region of high heat fluxes expands.
