HEAT AND MASS TRANSFER IN DISPERSE AND POROUS MEDIA EXPERIMENTAL AND NUMERICAL INVESTIGATIONS OF NONSTATIONARY EVAPORATION OF LIQUID DROPLETS

摘要

The results of experimental and numerical investigations of the nonstationary process of evaporation of droplets of pure liquids into a dry air at variable initial temperature of a droplet, temperature of the gas medium, and relative velocity of flow around a droplet are presented. The regions of application of the well-known laws of change in the size of an evaporating droplet in time depending on the thermal gas-dynamic conditions and thermophysical properties of the liquid and gas phases have been analyzed.
