| 摘 要： | 为深入研究静电场对基面液滴蒸发的作用,结合有关国内外研究现状,通过分析电场对基面液滴的变形作用和对液滴内部流动模式和速率的影响,以及电场对液滴在上述两方面的影响与液滴蒸发的关系,分析了电场对基面上液滴蒸发过程的强化作用,对有关基面液滴在电场下蒸发的研究进展进行了介绍,根据前人的理论和试验研究结果探讨了电场对基面液滴蒸发强化作用的基本机制:电场能够使基面液滴的表面电荷分布和形貌特征发生变化,发生电润湿现象,同时改变液滴的内部流动形态,提高液滴的内部流动速率,从而从两方面强化液滴界面处的热交换,促进液滴的蒸发传质.同时,简要评析了目前的研究进展情况,并指出关于电场强化基面液滴蒸发值得进一步研究的方向.研究结果为高热流密度表面的静电雾化冷却技术研究提供了思路.

| 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. |
