Abstract: An approach that allows to estimate the necessity of homogeneous nucleation process accounting/not accounting for evaporation intensity and to predict the direction (increase or decrease) of mass flux density change of evaporating matter has been proposed. A dimensionless parameter making it possible to determine the areas of increase/decrease of evaporation intensity in the presence of a homogeneous nucleation process is proposed. It is shown that for some substances (methanol, ethanol) the direction of process significantly depends on the nature of heat exchange between the formed droplets and the surrounding vapor droplets.

Keywords: homogeneous nucleation, evaporation, supersaturation degree.
