RESUMO

A physical model of heat transfer by bodies in a high-temperature heterogeneous flow is constructed by generalizing a large volume of empirical data. The studies embrace the range of Mach numbers 2.6−4.2 and the range of Reynolds numbers (calculated on the basis of the radius of the model) 0.2·106−5·106. The dimensions and concentrations of the disperse impurity are varied from 20 to 250 μm and from 0.1 to 1%, respectively.
