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.

This model example illustrates applications of this type that would nominally be built using the following products:
