The experimental data on the condensation of vapor from a gas–vapor mixture in the presence of an electric field are discussed. It is assumed that a corona discharge or, to be more accurate, its accompanying phenomena such as the unipolar charging of the medium and the electric wind, which produces intense mixing both of the medium and the condensate film, is the main factor influencing the intensification of the condensation in an electric field. The criteria of the similarity of the process, among which the main attention is drawn to the “electric” Reynolds number, which characterizes the interaction of the electric field with the medium, are considered. We also discuss the parameters of vapor–air mixtures, such as their density, viscosity, and ion mobility. A simplified method of the generalization of the experimental data on condensation in the presence of an electric field based on the concepts of a corona discharge is proposed.
