Abstract

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–ω turbulence model with reference to the experimental conditions. The calculations are carried out at Reynolds and Mach numbers Re=2× 105 and M∞=1.1, 1.3, and 1.7 and the experimental investigations at Re=1.62×105–2×105 and Mach numbers on the interval 0.7 ≤ M∞ ≤ 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.
