Experimental studies demonstrate intensified heat transfer in dielectric fluid boiling on modified surfaces under electric fields, suggesting improved efficiency.
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.
