Abstract
Averaged equations for gas suspension motion and equations of the k-e model of turbulence are reduced to a closed system of ordinary differential equations in the region of impingement of a flow on a body. Numerical simulation of impurity motion and heat exchange between a dust-containing gas flow and a wall in the vicinity of the critical point is carried out. The effect of the discrete component on the pulsation characteristics of turbulence is investigated. Results of calculations of the heat transfer coefficient as a function of the ratio of the heat capacities of the phases and the concentration and size of the impurity particles are presented.
