An experimental and theoretical study of the evaporation of non-ideal solutions droplets

Abstract

This work presents the results of an experimental study of the dynamics of evaporation of suspended droplets in the air stream. Droplets of pure liquids (water, ethanol) and their mixtures of various compositions are considered. Dependences of the size of droplets and their surface temperature on time in a wide range of velocities of the flowing stream and its temperature, as well as the variation of the composition of the droplets, are obtained. The paper presents a mathematical model used to compare the experimental data.
