Abstract
Steady high-Reynolds-number subsonic and supersonic flowfields about a circular cylinder mounted upright on a flat plate were simulated numerically by integration of the time-dependent three-dimensional compressible mass-averaged Navier-Stokes equations. Effects of turbulence were represented by a two-equation (k-e) closure model that included a generalized formulation and low-Reynolds-number terms. For the supersonic case, the turbulence equations incorporated a compressibility correction. Grid mesh step-size studies were performed to assess resolution requirements of the solutions. Comparison is made with experimental data in terms of static pressure and total pressure loss coefficients, velocity distributions, and surface limiting streamline patterns
