Abstract：In order to deeply study the effect of electrostatic field on the evaporation of basal droplet, this paper combines the research status at home and abroad to analyze the deformation effect of electric field on basal droplet and the influence of electric field on the internal flow mode and velocity of droplet, as well as the effect of electric field on the evaporation of basal droplet. The relationship between the influence of the above two aspects of the droplet and the droplet evaporation was analyzed, and the strengthening effect of the electric field on the evaporation process of the droplet on the base surface was as well analyzed, and the research progress of the droplet evaporation on the base surface under the electric field was introduced. Theoretical and experimental research results of the basic mechanism of the electric field on the evaporation enhancement of the droplet on the basal surface was discussed as follows: the electric field can change the surface charge distribution and morphology of the droplet on the basal surface, cause the phenomenon of electro-wetting to occur, while changing the internal surface of the droplet. The flow pattern increases the internal flow rate of the droplet, thereby enhancing the heat exchange at the droplet interface from two aspects as well as promoting the evaporation and mass transfer of the droplet. This paper briefly reviews the current research progress, and points out the direction of further research on the electric field-enhanced basal droplet evaporation. It further provides ideas for the research of electrostatic atomization cooling technology on high heat flux surfaces.
