摘要/Abstract

摘要： 暋采用白油和水为实验介质,利用显微高速摄像系统对高压交流电场油中水滴的喷射现象进行了研究。结果表明,液滴破裂喷射与电场强度及频率、油品黏度以及界面张力有关;液滴破裂时的临界锥角只与两相介电常数有关,本文约为38曘;随着频率增加、油品黏度增加以及界面张力的降低,子液滴的空间分布角度减小;液滴的喷射时间随液滴直径增大和油品黏度的增加而增加,黏度较低油品中,频率越低液滴喷射时间越长;喷射量随着液滴直径的增加而增加。

Abstract: Experiments were carried out to investigate the droplet jetting in oil under high voltage AC electric field with different types of white oil and water. With a micro highspeed camera system and image processing technology, the jetting of droplet was observed and analyzed. The results indicate that the droplet jetting is mainly affected by electric field strength, frequency, viscosity and interfacial tension. The critical cone angel of jetting is about 38°, which is only related to dielectric constant of oil and water. When frequency and oil viscosity is increased and interfacial tension is decreased the subdrops departing from mother drop will be smaller and distribute in a smaller angle. As droplet diameter and viscosity increasing, jetting time of small droplets increase. In oil with lower viscosity, the jetting time increase with the decrease of frequency. Jetting quantity of droplet increases with the increase of droplet diameter. 
