| Abstract: | An investigation has been made of hypersonic flow over spherically blunted cones in an atmosphere consisting of carbon dioxide and nitrogen. Local thermodynamic equilibrium is assumed in the shock layer. Account is taken of viscosity, diffusion, heat conduction, and radiative energy transport. The problem is solved using equations for dynamics of a viscous radiating gas without isolating inviscid flow and boundary-layer regions in the shock layer. The selectivity of the radiation is allowed for by using a two-stage approximation for the spectral dependence of the absorption coefficient, obtained by processing detailed data on absorption cross sections. The solution is found by a flow establishment method. Results are presented for flow over blunt cones with different semiangles. |
