A theoretical and experimental investigation of mixing and supersonic combustion is presented. A review of the problem under investigation is given. Then an analysis of inviscid flow fields with a finite rate chemistry for a hydrogen-air reaction is presented, an an analysis of a turbulent mixing for flows with large density gradients with no chemical reaction is presented. The analysis is compared wit the experimental results. Results of the experiments in upersonic combustion are presented. (Author).

The book discusses the results of theoretical and experimental studies of skin friction, heat transfer, and mass transfer in a turbulent boundary layer at supersonic gas velocities. At the same time the book presents the fundamentals of the molecular theory of gas flow. It gives derivations of the equations of turbulent flow and of boundary layer equations, in particular, for a multicomponent reacting gas. Information on the kinetics of chemical reactions in air is discussed. Problems of heat and mass transfer through permeable surfaces are also discussed.

Heat-transfer coefficients in the form of Stanton number and boundary-layer transition data were obtained from a free-flight test of a 100-inch-long 10° total-angle cone with a 1/16-inch tip radius which penetrated deep into the region of infinite stability of laminar boundary layer over a range of wall-to-local-stream temperature radius and for local Mach numbers from 1.8 to 3.5. Experimental heat-transfer coefficients, obtained at Reynolds numbers up to 160 x 106, were in general somewhat higher than theoretical values. A maximum Reynolds number of transition of only 33 x 106 was obtained. Contrary to theoretical and some other experimental investigations, the transition Reynolds number initially increased while the wall temperature ratio increased at relatively constant Mach number. Further increases in wall temperature ratio were accompanied by a decrease in transition Reynolds number. Increasing transition Reynolds number with increasing Mach number was also indicated at a relatively constant wall temperature ratio.
