Theoretical Analysis and Experimental Verification on Flow Field of Piezoelectric Pump with Unsymmetrical Slopes Element被引量：18
《Chinese Journal of Mechanical Engineering》2009年第5期735-744,共10页XIA Qixiao ZHANG Jianhui LEI Hong CHENG Wei 
supported by National Natural Science Foundation of China (Grant No. 50575007, Grant No. 50775109)
Regular valveless piezoelectric pumps have rectifying elements outside their chambers to produce net flow. These rectifying elements outside the chamber will increase the overall volume of the pump and prevent its min...
