【 摘 要 】

Results of numerical simulation of shock-wave pattern and vortex structures forming in supersonic flow past a cylindrical body, which penetrates the approaching flat-plate boundary layer up to the plate, are presented. The laminar flow case with Mach number of 2.95 is considered. Comparison of numerical solutions obtained with the AUSM and HLL schemes of the first and second accuracy order are conducted. Solution grid sensitivity issues are discussed.
