Study of the mechanism of the particle—substrate interaction in the case of the impact of a supersonic heterogeneous flow on a flat solid wall

Abstract

The mechanism of the interaction between a particle and a flat substrate in the case of the inleakage of a supersonic heterogeneous flow to a solid wall is studied. The equation of energy balance in the area of particle impact on the substrate is considered. This makes it possible to calculate the weight-averaged temperatures of the heated particle segment and also the average temperature of the heated substrate segment in the contact area during the impact. This equation is an adequate mathematical model of the physical process of special-coating deposition on different metal surfaces, including the structural components of air- and spacecraft, by the gas-dynamic method at low temperatures.
