摘要：
The supersonic perfect-gas flow past a circular cylinder is studied on the basis of a numerical analysis of the time-dependent two-dimensional Reynolds equations using a differential q-omega turbulence model with reference to the experimental conditions. The calculations are carried out at Reynolds and Mach numbers Re = 2 x 10(5) and M(infinity) = 1.1, 1.3, and 1.7 and the experimental investigations at Re = 1.62 x 10(5)-2 x 10(5) andMach numbers on the interval 0.7 <= M(infinity) <= 1.7. The calculated and experimental data on the pressure coefficient distribution over the cylinder surface, the location of the separation point on the surface, and the pressure drag coefficient are compared.
