Computational analysis of a piezo-electrically actuated valve-less micropump is carried out for microfluidic applications. The effect of the operating parameter frequency on the performance of micropump is studied. The valve-less micropump consists of nozzle/diffuser elements; the pump chamber; a thin membrane (diaphragm) and a piezoelectric disc, PZT 5A of diameter 12 mm as the actuator. The complete electric–fluid–solidcoupling model is simulated with the commercial finite element analysis software COMSOL Multiphysics 5.0 to investigate the performance of the micropump.
