Extensive research has investigated the enhancement of boiling heat transfer through electric fields, primarily focusing on the effects of direct current (DC) electric fields. This study seeks to deepen the understanding of the mechanisms involved in boiling heat transfer enhancement when using alternating current (AC) electric fields. By examining the deformation of bubbles in uniform electric fields and the electric potential distribution at the bubble edges, we assess the impact of electric field strength and frequency on boiling heat transfer. The variation in density and dielectric constants between the gaseous and liquid phases results in a polarization charge density at the bubble boundary, causing the bubbles to elongate in the direction of the electric field. Our findings reveal that the electric field not only induces significant bubble deformation but also facilitates bubble detachment, thereby enhancing heat transfer. Specifically, the electric field influences the diameter of detached bubbles, leading to a reduction in size and an increase in detachment frequency, which collectively contribute to improved boiling heat transfer.
