Abstract
In this study, a new magneto-hydrodynamic (MHD) micro-device with simultaneous mixing and pumping capability is proposed, and a numerical investigation for the performance of the device is performed. The present MHD micro-device utilizes the arrays of electrodes deposited on duct walls. By judiciously applying different potentials to different electrode pairs, the Lorentz-force can be created, directing the liquid to move in a desired path for pumping without a need of separate pumps, and simultaneously inducing complex flows for mixing. The results show that the micro-device proposed in this study can achieve highly-efficient, simultaneous mixing and pumping for electrolytes.
