近幾年來物件越作越小，當微小物件需要流體進入或是輸出時，則需要微管道把流體導入或輸出。本篇研究主要在於在不同的入口氣體壓力和入口流速為變數的考量下，對空氣進入微流道後，微流道各點壓力和速度之模擬，再由管內的壓力與速度模擬出空氣作用於微流道的等效應力，利用等效應力取得流道板的壽命，進而確保微流道在使用上能有一定的效率。模擬採用有限元素法，但考慮到微流道有Slip-flow邊界條件效應，故不宜採用傳統邊界速度為零之方式，而採用邊界速度 ，模擬法與實驗結果作比較，其誤差率在15%以下。

Nowadays, the components are made more and more small, the flow import or exports through the components are required frequently, so a set of micro-channel is need. The main aim of this paper is to study the effect of different inlet pressure and inlet flow velocity of micro-channel. By using the proposed numerical simulation, the pressure, velocity and equivalent stress inside the micro-channel corresponding to different inlet pressure and inlet velocity can be obtained. Also, the life of micro-channel was discussed also. Due to the size effect of the micro-channel, the boundary condition is set as . The error between the simulated and experiment results in less than 15%.
