Abstract
Heat exchange between the shock-compressed layer of pulse plasma and nickel particle of 60 pm size was studied. Numerical analysis of the characteristics of pulse plasma formed in the plasma-detonation accelerator has been performed. Influence of various components of heat exchange at particle heating in pulse plasma has been determined. The influence is shown of radiation heat exchange on heating of discrete particles and sprayed surface.
Keywords: plasma-detonation spraying, pulse plasma, dis¬perse particle, heat exchange, heat flux, radiation
