ABSTRACT

This chapter assumes the boundary layer to be thin, both physically and optically, and hence limit our consideration to inviscid and adiabatic flows. A vast majority of inviscid shock layer flow studies have been carried out in two-dimensional formulation and, apart from a few planar analyses, are usually concerned with axisymmetric geometries. F. D. Popov considered the steady, hypersonic inviscid flow of a nonadiabatic gas about a two-dimensional flat body and used the radiative heat conduction approximation to account for the radiation aspect of the problem. Radiative transfer calculations, based on the tangential slab approximation, account for both line and continuum contributions, and yield the dependence of radiative heat fluxes on the freestream conditions and on principal curvature radii of the configuration. O. M. Belotserkovskii and V. N. Fomin were concerned with both axisymmetric and three-dimensional hypersonic radiating airflows over different configurations. In some cases, the effect of mass injection from the body surface is included.
