Abstract
An analytical solution is found for equations of AC and DC-operated MHD micropump with circular channel. The kind of fluid is Newtonian and the flow generated by the Lorentz force is assumed to be laminar, unidirectional, and one-dimensional. The effect of Hartman number and radius is studied on the velocity and volumetric flow rate profiles and a relation for optimum Hartman number and radius which causing maximum volumetric flow rate is found. Finally DC-operated MHD micropump is compared with AC-operated.
