The pulsations of droplet size in diesel-water emulsions under the action of a high-frequency electric discharge have been studied using high-speed video recording. The discharge leads to the dispersion of emulsion droplets with a high water content, in contrast to droplets of pure combustible liquids. By processing video recordings of the evaporation process, the time dependence of the projection-equivalent droplet size was determined. The results of this study can be used in further investigations of the spray combustion of emulsion droplets when an additional high-frequency electric discharge is applied at the atomization stage.
