【 摘 要 】

There is a big difference between electrostatic atomization and other conventional atomization such as mechanical and air flow atomization. The mechanisms underlying the rupture and atomization of Newtonian fluid jets in the electric field have not been well understood. In this study, we experimentally evaluated the diameter of the droplet produced by charged jet breaking up in electric field, and obtained an empirical relationship between the flow rate and droplet diameter. These results may provide theoretical guidance to further understand the mechanism of liquid atomization in the electric field, and be of great significance to promote the application of electrostatic atomization in the field of atomization.
