The micropump considered here is actuated by the vibration of membranes and can generate a net flow along the optimized rigid fluidic channel. The detailed layout of the micropump channel is optimized with respect to a number of factors which influence the output net flux of liquid  such as the number of actuation elements  the positions of actuation elements  the driving phase differences and the driving frequency. Accordingly  the layouts of several novel valveless micropumps are presented. 2011 IEEE.   Integrated microfluidic chip for endothelial cells culture and analysis exposed to a pulsatile and oscillatory shear stress 期刊论文  OAI收割 LAB ON A CHIP, 2009, 卷号: 9, 期号: 21, 页码: 3118-3125 Shao, JB; Wu, L; Wu, JZ; Zheng, YH; Zhao, H; Jin, QH; Zhao, JL 收藏  |  浏览/下载：24/0  |  提交时间：2011/12/17 SOFT LITHOGRAPHY  FLOW  DEVICE  PERMEABILITY  SYSTEM  MICROPUMPS  COCULTURE  MOLECULE  ADHESION  BARRIER   Simulations and experimental studies of diffuser/nozzle pumps (EI CONFERENCE) 会议论文  OAI收割 4th International Symposium on Precision Mechanical Measurements, August 25, 2008 - August 29, 2009, Hefei/Jiuhua Mountain, Anhui, China 作者:  Li W.;  Li W. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 An investigation of diffuser/nozzle micropumps is presented. Numerical simulations are done using CFD program ANSYS/Flotran. The simulations show when the opening angel is small  the flow in the diffuser/nozzle is steady  the mass flow is increasing with the adding opening angle. But when the opening angel continues increasing  the pressure grads will be bigger than zero. It means that the static pressure is gradually going up along the diverging direction. The fluid near the wall stops flowing because the velocity decreases rapidly and the dynamic pressure is not big enough to overcome the increasing of the static pressure. Finally the fluid flows reversely from the backward position of higher pressure area  this makes the separation flow of fluid  the diffuser is full of reverse fluid. And this results in the dropping of mass flow at last. The simulations also show that the performance of diffuser with a round inlet is better than that with a sharp inlet. The mass flow of micropumps with different opening angles  different inlets are measured. The experimental results agree well with the simulations. 2008 SPIE.
