Effect of radiation on flow near stagnation point
1971
We consider the problem of hypersonic flow about a blunt body with account for radiative energy transport. In the absence of absorption of radiation in the compressed layer, even for small optical thickness of the gas, as is known [1], physically incorrect solutions are obtained, since the gas enthalpy at the stagnation point on the body becomes zero. This takes place because the gas element on the zero streamline irradiates its energy completely. Naturally, the contradiction which arises in the absence of absorption must be resolved within the radiation scheme itself and is not removed, generally speaking, with the introduction of additional physical limitations.
