DESIGN OF AN EFFICIENT AC MAGNETOHYDRODYNAMIC STIRRER
Abstract
Rapid mixing of two or more analytes in microchannel networks is essential in the design of most biochemical, immunoassays and DNA analysis microsystems. In this paper we report numerical simulations of a chaotic magnetohydrodynamic (MHD) stirrer that exhibits fast mixing of steady pressure-driven flows in microchannels at medium-low Reynolds number. The proposed mixer is benchmarked against a MHD stirrer prototype recently reported in literature. Numerical results show that the proposed device has a higher and faster mixing efficiency with respect to recent literature.
