Abstract

The article presents the results of experimental studies of heat transfer during boiling of a dielectric fluid in an electric field on modified surfaces obtained by electrospark alloying. The influence of the electric field strength, electrode shape, interelectrode distance, heat-transfer surface material, roughness parameters, and other factors on the heat-transfer characteristics and the development of the boiling process was studied. A comparative analysis of the influence of the electric field and structural modification of the heat-transfer surface on heat-transfer intensity is presented. Heat-transfer intensification achieved was up to 3.5 times higher compared to that at boiling on a smooth surface in the absence of a field. Based on visual observations and high-speed filming, the mechanism of boiling in an electric field on modified surfaces is discussed.
