POLYEMPIRICAL THEORY OF HEAT EXCHANGE OF A THIN PLATE AROUND WHICH FLOWS A RAREFIED GAS AT HIGH MACH NUMBER (POLUEMPRICHESKAYA TEORIYA TEPLOOBMENA TONKOI PLASTINY, OBTEKAEMOI RAZREZHENNYM GAZOM, PRI BOLSHIKH CHISLAKH MAKHA),

Abstract

The problem of heat transfer to an infinite cooled flat plate in hypersonic rarefied gas flows at zero angle of attack is considered. A theoretical analysis of a flow model and heat transfer is developed on the basis of the results of a series of experimental investigations, assuming that the plate thickness is very small as compared with the mean free path of molecules in a free flow, the values of the interaction parameter are rather high, and the surface temperature is constant everywhere. The boundaries between single collisions and transition zones are approximately established and the effect of rarefaction on their relative importance is considered. (Author)
