When we consider to pass the particle suspension over a microelectrode, electric fields to produce a motive force are used. If the suspension has a noticeable conductivity, the electric field drives a substantial conduction current through the fluid and then the electric current generates localized Joule-heating. The resulting temperature gradient produces local conductivity and permittivity changes in the fluid. Dielectrophoretic forces will produce motion of both the fluids and the particles. Furthermore, the buoyancy force due to temperature field affects the flow field. In this paper, we study AC dielectrophoretic flow with the aid of finite element analysis software COMSOL Multiphysics which is a commercial package and can be considered to suit to simulate multiphysics.
