| 摘 要： | 介绍了无阀微泵的特点及其工作原理，提出一种应用于无阀微泵新型锯齿形流道.针对锯齿形流道不同开口角度，用CFD(computational fluid dynamics)软件进行了仿真模拟，得出了流道内速度和压力变化规律.分析了压力和流量的分布特征及关系曲线，为锯齿形流道微泵理论研究和优化设计提供了依据，并与单级锥形扩散/收缩流道作对比.结果证明，此锯齿形流道相对于锥形扩散/收缩流道可以提高微泵效率.

| Abstract: | The operating principle and flow characteristic of valveless micropumps are introduced. A new type of saw-tooth channel for valveless micropumps is proposed. The saw-tooth channel in different angels is simulated with the CFD (computational fluid dynamics) software. The velocity and pressure distributingare presented, and the characteristic curve of the pressure and flow rate drawn compared with the single taper pipe. The results show that the saw-tooth channel can enhance efficiency of the micropumps in comparison with the diffuser/nozzle channel. It provides a reliable basis to theoretical study and optimal design of saw-tooth micropumps. |
