This paper presents the results of an experimental study of the evaporation rate of suspended droplets pure water and a binary ethanol-water solution under conditions of forced convection (Re > 100). The results are compared with experimental data of other authors on evaporation of pure liquids. The evaporation rates of pure water droplets at different velocities of the flowing stream are measured. The dependence of the evaporation rate on the concentration of the less-volatile component is studied and the degree of the speed of the oncoming flow on the evaporation efficiency is estimated. A generalization of the experimental data shows that with an increase in the velocity of the incoming flow, the rate of evaporation slightly increases, but the change in the parameter A is not linear, and with an increase in the velocity, the rate of its increase noticeably decreases. Note that with the evaporation of ethanol-water solutions, the number of factors influencing the rate of evaporation increases, which complicates the generalization of data and the conduct of computational studies.
