Electroosmotic Flow in Porous Media

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.

Combined surface and arrow surface plots showing the velocity distributions in the cell with an applied electric field.
