In this study a numerical analysis has been conducted for the flow characteristics and pumping
performance of a piezoelectric-based micropump with electromagnetic resistance exerted on
electrically conducting fluid. Here, electromagnetic resistance is alternately applied at the inlet and
outlet with alternately applied magnetic fields in association with the reciprocal membrane motion of
the piezoelectric-based micropump. A model of Prescribed Deformation is used for the description
of the membrane motion. The internal flow characteristics and pumping performance are
investigated with the variation of magnetic flux density, tube size, displacement of membrane and
the frequency of the membrane. It turns out that the current micropump has a wide range of
pumping flow rate compared with diffuser-nozzle based micropumps.
