Numerical investigation of the influence of convection in a mixture of combustion products on the integral characteristics of the evaporation of a finely atomized water drop

A model of the heat-and-mass transfer in the neighborhood of a finely atomized water drop moving through the high-temperature products of combustion of materials has been developed for numerical analysis of the macroscopic mechanisms of movement of such a drop in a mixture of combustion products and water vapor with account for the complex of interrelated physical processes and phase transitions taking place in this case. The influence of the convection on the integral characteristics of the evaporation of the indicated drop was analyzed and the sizes of its "temperature" and " concentration" wakes were estimated. The conditions under which the integral characteristics of the evaporation of this drop can be calculated in the diffusion approximation were determined.
