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.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
