Аннотация

The results of RANS computations of a supersonic flow of a cylinder fixed between parallel plates are given. The Mach number of the incoming flow is M = 1.85. Methodological data on the effect of the grid resolution and turbulence model on the predicted structure of viscous-non-viscous interaction are obtained. Parametric calculations were performed for several values of the relative distance between plates. Three-dimensional effects arising from the interaction of boundary layers with the leading edge of the cylinder are studied. The flow structure is shown to change qualitatively when the distance between the plates decreases — an additional “hanging” compression shock is formed, the length and height of the separated-flow region increases, and the area of high heat flows expands.
