[1] Heat exchange on the front surface of a blunt body in a high-speed flow containing low-inertia particles / E. B. Vasilevskii, A. N. Osiptsov, A. V. Chirikhin, L. V. Yakovleva // Journal of Engineering Physics and Thermophysics. — 2001. — Vol. 74, no. 6. — P. 1399–1411. The method and results of an experimental investigation of the heat exchange on the front surface of a sphere in a supersonic flow containing particles of diameter d = 0.12-2.4 ∎m and hollow particles of d = 160 ∎m are presented. It has been revealed that in the case where even very small particles of d = 0.15 ∎m are contained in an undisturbed flow and their concentration is low (of the order of a percent), the heat flux in the region of the critical point of the model markedly increases. A comparison of the experimental data with the data of calculations of the heat exchange in the region of the forward critical point which are based on the theory of a two-phase laminar boundary layer has been made. A glow near the surface of the model was observed in the experiments conducted in total darkness.
