Interaction of the Boundary Layer with an External Flow Caused by Radiative Heat Transfer

摘要

The laminar boundary layer on the surface of a wedge streamlined by a hypersonic flow of radiative gas is studied with the assumption that the effect of radiation on gas flow in the disturbed region is small. It is assumed that gas radiation is independent of its motion in front of the density shock. Only that range of temperatures where the radiation pressure and density of radiant energy may be neglected is considered. In order to separate the effect of interaction of the boundary and shock layers brought about by radiant heat exchange the boundary layer is considered to be thin and the effect of its displacement thickness on the shape and parameters of the shock wave is neglected. The temperature of the wedge surface Tw, the Prandtl number P and the product of gas viscosity times its density are taken constant.
