Abstract

Abstract: In order to study the microscopic movement process of Taylor cone in the process of electrostatic atomization, the formation and fracture of Taylor cone in different liquid electrostatic atomization process were studied by using the cavity electrostatic atomizer.The Taylor cone taper angle,the relationship between the length and the minor axis, the cone formation and fracture cycle and other related parameters were analyzed.The results show that the formation and fracture of Taylor cone are divided into two stages: energy storage and fracture.The discharge field strength, liquid viscosity and surface tension are the main factors affecting the Taylor cone formation and fracture.The viscosity and surface tension of liquid, the charge distribution in discharge space, the distribution of discharge field strength and the surface charge distribution of Taylor cone determine the final shape and period of motion of the Taylor cone.

Key words: Taylor cone, fracture cycle, the relationship between the length and the minor axis, Taylor cone angle, droplet diameter
