摘要:

设计出用于无阀压电微泵的锯齿型流道结构.采用正交设计方法,以数值模拟得出的流量和压力数据为指标,对不同流道宽度、深度、长度、锥角和扩张角组合进行极差和方差分析,得出几种结构参数的最优水平组合以及各参数的显著性水平,从而达到对流道结构的优化.最后用仿真模拟方法验证了该最优组合的有效性.

Abstract:

The structure of sawtooth microvalve used in valveless micropump with piezoelectric actuator is designed. The orthogonal design is adopted in optimizing the structure. Using the data of flow rate and pressure loss obtained in computational fluid dynamics (CFD) simulation, the range analysis and variance analysis of the different combination of width, depth, length, taper and diffuser angle are performed. The optimal level combination and signicifance level of several structural parameters are obtained. Availibality of the optimal combination is testified in simulation.

Key words: valveless micropump; sawtooth channel; orthogonal design; structural optimization
