Abstract

The flow past a circular cylinder with an isothermal surface at Mach numbers M∞=2 and 5 and Reynolds numbers ranging from 104 to 108 is investigated on the basis of the Reynolds equations using a differential two-equation turbulence model. The effect of flow turbulization on the separation point displacement, the separation zone length, the maximum velocity reduction in the separation zone, and the increase in the heat flux at the rear stagnation point is determined.
