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.
