Piezoelectric diffuser/nozzle micropump with double pump chambers

WANG Wei, ZHANG Ying, TIAN Li, CHEN Xiaojie, LIU Xiaowei

Frontiers of Mechanical Engineering 2008, Volume 3, Issue 4, Pages 449-453 doi: 10.1007/s11465-008-0076-4

Abstract: valve clogging, diffuser/nozzle elements are used for flow rectification in a valveless diffuser/nozzle micropumpHowever, the application of this type of micropump is restricted because of its pulsating or periodicIn this paper, a diffuser/nozzle Si/Glass micropump with two pump chambers by IC and MEMS technologyThe driving force of the micropump is produced by the PZT piezoelectric actuator.The result indicates that the micropump achieves great performance with the actuators working at anti-phase

Flow behavior of liquid-solid coupled system of piezoelectric micropump

LU Lijun, WU Jiankang

Frontiers of Mechanical Engineering 2008, Volume 3, Issue 1, Pages 50-54 doi: 10.1007/s11465-008-0003-8

Abstract: paper employs a shallow water model and the finite element method to approximate periodical flows of a micropumpA liquid-solid coupled system equation of the micropump is presented.Based on the thickness-averaged flow equation, the periodical flow of the micropump is studied usingNumerical results indicate that an optimal working frequency can be obtained, at which the flow rate of the micropump
