Heat transfer in the neighborhood of the stagnation point under conditions of hypersonic heterogeneous slip flow past bodies

This paper integrates extensive experimental and theoretical data on heat transfer on the surface of blunt bodies subjected to hypersonic heterogeneous flow. The value of the Mach number of the carrier gas flow is varied from 2.4 to 6, and those of the Reynolds number calculated by the diameter of the body subjected to flow, from 10(4) to 10(6). The mass concentration of solid impurities in the flow does not exceed 3%. When the particle diameter varies from 0.15 to 160 mum, the rate of particle collisions with the body surface varies from zero to 1350 m/s. An analysis of the experimental data helps develop the phenomenological model of heat transfer on the surface of a blunt body in a hypersonic heterogeneous flow.
