Abstract
We use the software CFDRC to do the research about the valveless micropump which is driven by piezoelectrical materials. We also modify valveless micropump to other type valveless micropump and compare flow rate in each frequency. In order to increase the flow rate, we connect two valveless micropumps in serials and run in anti-phase mode and double frequency mode to obtain large flow rate. Double frequency mode is that one piezoelectrical material runs in f KHz and another runs in 2f KHz with phase angle different. The flow rate of anti-phase is 134 uL/min in 4.8 KHz, and flow rate of double frequency is 244 uL/min in f=3.4KHz . The efficiency of double frequency mode is higher than that of anti-phase mode.
