Abstract

The processes of heat and mass transfer and phase transformations during motion of a set of water droplets through high-temperature gases have been studied numerically. The regimes and conditions of formation of zones of significant joint influence of the droplets on the integral characteristics of heat and mass transfer are determined. The values of the dimensionless parameters describing the dependence of the temperature of the gases in the wake of a small set droplets on their volume concentration and arrangement are calculated. The variations in these dimensionless parameters during motion of droplets through high-temperature gases are described.
