Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

The problems of heating and acceleration of the particles of refractory materials to provide the process of high‐velocity flame spraying are considered. Based on numerical investigations, recommendations on selection of fuel components are given. Estimates of the flow rates of fuel components and the geometric parameters of a gasdynamic circuit, which provide the acceleration and melting of the particles in accordance with their size and mass fraction, are presented.
