Consideration of radiation in problems of flowing of blunt-nosed axisymmetric body by hypersonic gas flow

Abstract

When bodies move with large supersonic velocities, the gas between the body surface and the shock wave is heated to several thousand degrees Celsius. At such temperatures, the heat exchange by radiation between gas particles, as well as between the gas and the body surface, has a significant effect on the gas parameters in the shock layer. In this case, in order to solve the problem of streamline of a blunt-nosed body by a hypersonic gas flow, it is necessary to involve the full system of gas dynamics equations taking into account gas viscosity and thermal conductivity and radiation field.
