[2]Dept. of Electrical Engineering and Computer Sciences, Northern Arizona University, Flagstaff, Arizona, USA

This paper presents the approach taken through the utilization of COMSOL Multiphysics 3.5a, to develop a model that simulates the flow of a magnetorheological (MR) fluid through a micro-channel. The model was developed as an aid in the analysis of a micropump that produces flow by means of displacement of a MR fluid slug within a microchannel.
