Abstract

This paper reports a lumped-parameter mathematical model for a magnetohydrodynamic (MHD) micropump being developed by the authors. The micropump can be used to deliver electrically conductive fluids. The major advantage of a MHD based micropump is that it does not contain any moving parts. It may have potential applications in medicine delivery, biological and biomedical studies. To develop a design guideline for the MHD micropump, it is desired that the dynamic behavior of the flow in a microsystem driven with MHD body force. A bond graph model has been developed for the MHD micropump. A commercial software, 20 SIM, was used as the simulation tools. The simulation results for two different sizes of micropumps with a 1 percent salt-water solution used as a pumping fluid are presented in the paper.
