Abstract
This paper considers issues connected with the simulation of the motion and heat exchange of disperse impurity particles in nonisothermal gas and low‐temperature plasma jets under the action of turbulent pulsations of the carrier flow. The influence of the outflow conditions, the initial parameters of the phases, and the conditions of particle injection into a jet flow on the laws of impurity scattering and heat exchange are investigated. The results of the numerical calculations are compared with the data obtained without taking into account the influence of turbulent pulsations on the particle motion.
