| Abstract: | Numerical simulations of supersonic and hypersonic inviscid flow over blunt nosed bodies are investigated by an upwind scheme of the compatibility relations for the three dimensional method of characteristics. An inverse method is used to compute the flowfield behind the detached shock and the method of axisymmetric characteristics is used to determine flow parameters on the initial value surface.The results of numerical examples agree comparatively with the experimental data. |
