Modeling of 3D AC electro-osmotic pumps is relevant to the creation of portable or implantable lab-on-a-chip devices for mm/s tunable fluid flows attainable with battery scale voltages. In this analysis using COMSOL Multiphysics we investigate the modeling challenges of computationally calculating systems of fluid flow phenomena governed by AC Electroosmosis in the micro and nano scale regimes.
