匀强电场下分散相液滴的聚并
Coalescence of dispersed phase droplet under uniform electric field
摘要
Abstract
To explore the influence of operation parameters on the movement and coalescence of droplets, the effects of electric field intensity,droplet size,distance and relative location between two droplets on coalescence were numerically investigated by the volume-of-fluid(VOF)method to track the interface and by leaky dielectric model to simulate the electric field.The factors of electric field intensity,droplet size,droplet surface spacing and droplet relative position on the droplets coalescence were analyzed theoretically and compared with the numerical results.The results indicate that the efficiency is increased with the increasing of electric field intensity and decreased with the increasing of droplet diameter ratio, distance and relative angle between two droplets.The influence of field intensity on coalescence is complicated.When the electric field intensity is large enough,the two droplets can not produce coalescence process,and the droplet is elongated or rebounded by the other droplet.There is a critical value of electric field intensity for droplets coalescence.关键词
