Heat Transfer Processes in High-Temperature Flows of Two-Phase Media
ABSTRACT
The results of an experimental study and theoretical analysis of specific features of heat transfer in inner and outer supersonic high-temperature turbulent flows of heterogeneous flows are presented. The experiment is conducted on a high-temperature setup by means of laser diagnostics which allowed one to obtain fluctuation characteristics of the flow and also to determine substantial enhancement of heat transfer within a range of 10−85% with an increase in particle concentration from 3 to 15%. It is shown that the presence of solid particles with a diameter of 40−50 μm in a supersonic flow leads to an increase of the degree of turbulence and to a substantial change in the structure of a wall surface.
