Electroosmotic Flow in Porous Media

Application ID: 11

This example treats the modeling of electroosmotic flow in porous media. The system consists of a compartment of sintered porous material and two electrodes that generate an electric field. The cell combines pressure and electroosmotic driven flow.

The equations that are solved are the continuity equations for flow velocity and current density together with a mass balance using the Electrokinetic flow application mode. The stationary velocity and potential fields are used in the transient simulation of the concentration of a charged tracer species injected into the system.

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.
