The experimental data for 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 precise, its accompanying phenomena such as unipolar charging of the medium and the electric wind, which produces intense mixing both of the medium and condensate film, is the main factor influencing the intensification of condensation in an electric field. Criteria of 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 density, viscosity and ion mobility. A simplified method of generalization of experimental data on condensation in the presence of an electric field, based on the concepts of corona discharge, is proposed.
