Development of Electric Field Non-Contact Stirring Technique (E.N.S.) for Fine Particles Applied Abrasive Control Technique with AC Electric Field

Abstract

In this study, we aim to develop innovative stirring technology (electric field non-contact stirring technique (E.N.S.)) applied abrasive control technique with AC electric field. This technique allows for stirring without contact by applying AC electric field to droplets. We examined observation of fundamental behavior and inside behavior for droplet by AC electric field and investigated the feature of electric field non-contact stirring technique as parameter frequency and voltage, quantitatively.  As a result, we found that applied voltage affected magnitude of the attractive force acting on droplet, and the resonant frequency of droplet was greatly affected amount of droplet and bottom diameter of droplet, and there is no increase in the droplet temperature, and the motion speed of particles in droplet was accelerated by this stirring technology.
