Shielding of radiation by a boundary layer on bodies of different form

A method is developed for calculating heat transfer in a viscous, heat-conducting radiative shock layer on the front surface of a blunt body. The method is based on the combination shock-layer model of Satton (1974) and provides separate solutions for the inviscid flow equations pertaining to the body itself as well as the boundary layer equations. The boundary layer equations are coupled with relations describing the mechanisms of destruction of the material on the surface of the body. Some of the laws governing the shielding of radiant flow by a boundary layer are studied in bodies of different shapes, (a sphere and a spherically blunted cone), and the results are discussed. Finally, similarity properties are established for the radiation of shielding factor of a boundary layer on the surface of bodies disintegrating due to heat.
