Experiments were carried out to investigate the deformation of single drop in high voltage AC electric field with different types of white oil and water. The effects of electric field strength, viscosity of oil, interfacial tension and droplet diameter on the deformation of droplet were studied. With a micro highspeed camera system and image processing technology, the deformation of droplet was observed and analyzed. The results indicate that the deformation is mainly affected by electric field strength, drop diameter and interfacial tension. The eccentricity of ellipsoid drop is approximately proportional to the power of the electric field strength, N (1.7＜N＜2.4), and the diameter. The drop with lower interfacial tension is more prone to deform in the electric field. The effect of oil viscosity on droplet deformation is not obvious. When the deformation is small, the change of drop eccentricity is accordance with the change of Weissenberg number, but the phenomenon is different when the deformation is large.%采用不同的白油和水为实验介质对高压交流电场作用下单液滴的变形特性进行了研究.研究了电场强度,油品黏度、界面张力以及液滴直径等因素对液滴变形度的影响规律,并利用显微高速摄像系统结合图像处理技术对单液滴的变形规律进行了观察和分析.结果表明:液滴变形度主要受电场强度、液滴直径以及界面张力等的影响.与电场强度的N(1.7展开▼
