Abstract : An inverse method was developed for treating gas-particle supersonic flow past axisymmetric blunt bodies. This method is based on two transformations (von Mises and an additional one), which are convenient for determining the shock-layer flow fields and the body shapes. In using the present method, the pure gas flow fields around spheres were first solved numerically for the freestream Mach numbers = 10, 6, 4, 3, 2 and 1.5. These were found to be in very good agreement with the available results of Van Dyke and Gordon. Then the gas-solid-particle flow in the shock layer around blunt bodies (nearly spheres) were solved for the freestream Mach numbers = 10 and 1.5, with freesteam loading ratios = 0, 0.2, 0.5 and 1.0 and particle diameters 1, 2, 5 and 10 micrometers respectively.
