Mixing and Separating Operation between Two Liquid Layers in a Channel by Use of Electromagnetic Force

Abstract

A new process for mixing and separating operation between two liquid layers are proposed, where both a direct electric current and a stationary magnetic field are imposed. An electromagnetic force appearing upward or downward can be utilized for scattering phenomena in a mixing region, controlling of buoyancy in a keeping region, and absorbing behavior in a separating region.
In scattering phenomena, a liquid dome created by an upward force is broken to become many metal droplets. The electromagnetic force necessary to scatter is several times to a gravitational force.
In controlling buoyancy process, about 40% of imposed electromagnetic force is effective for controlling upward velocity or downward velocity of liquid droplets.
In separation phenomena, a liquid droplet on the interface can be absorbed to metal layer by a downward force where the energy due to electromagnetic force can overcome the surface energy.
