| Abstract: | The concept and corresponding model of a novel valve-less micropump are presented in this paper. It employs the flow principles of synthetic jet to realize control of flow direction, the structure is simple and the working frequency is high. Numerical simulation and analysis about the pump are conducted and the results show that the flow rate of the pump is high. When the working frequency is at 1000 Hz and Reynolds number is as 2500, the pumping flow rate for air can reach to 6 L/min. |
