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.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the 製品仕様一覧 and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
