Abstract
An analytic model of evaporation of a spherical droplet into the surrounding gas without consideration of the Stefan flow and vapor buoyancy is presented. This model is based on the use of the diffusion equation and contains a kinetic description of the evaporation process. In addition, this model is based on the assumption that droplet temperature does not change over time. In the framework of the presented model, an equation for the rate of droplet evaporation that is an alternative to the Fuchs equation is obtained. Analysis of the model showed that, depending on droplet size, evaporation can take place in three regimes.
