Abstract

The quasisteady evaporation of drops in a binary gas mixture is investigated at arbitrary Knudsen numbers. The analysis is based on the solution of kinetic equations with collision integrals in the Boltzmann form by Lees's method [9]. The obtained solution makes it possible to consider an arbitrary model of intermolecular interactions. Formulas for the evaporation time of the drops are analyzed, the model of rigid elastic spheres being used for the interaction of the molecules.
