Investigation on Water Droplet Jetting in Oil under High-Voltage AC Electric Field
摘要
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.关键词
