Abstract:

The method of integral relations is applied to the solution of hypersonic air flows past blunt, axisymmetric bodies with radiation taken into account. The calculation procedure is based on the use of an approximation of functions along the shock layer. The limiting state of the gas volume luminescence -- in which absorption can be neglected -- is considered. A complete system of gasdynamic equations describing the inviscid, non-heat-conducting, equilibrium, nonrelativistic gas flow is derived and solved in the second approximation. Calculations were carried out for the flow region limited by the shock wave, symmetry axis, the surface of the body, and the characteristic drawn between body and shock wave with and without taking radiation into account in order to check the accuracy of the analytical procedure. The maximum discrepancy of 2 - 3 was found on the boundary characteristic in the region of its intersection with the shock wave. In all other points in the flow the error was found to be about 0.5.
