Separation Through Electrocoalescence

Application ID: 8592


Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water.

To model electrocoalescence, you need to solve the Navier-Stokes equations, describing the fluid motion, as well as track the interfaces between the immiscible fluids. In order to include the electric forces, you also have to solve for the electric field. The electric field depends on the position and shape of the water droplets. This complex multiphysics process can readily be set up and solved with COMSOL Multiphysics.
