本次研究流體在微流道流動中壁面粗糙度與壓力變化之關係，這項研究主要分為兩部份：（1）不同粗糙度之微通道製造。 （2）微通道內流動壓力降量測 。在實驗中將以微機電的加工方法製作不同粗糙度的微通道壁面，探討微流體流動中粗糙度與壓力降的穩態關係。
實驗的結果吾人可發現，在微通道中粗糙度越大則壓力降越

大，而雷諾數對摩擦係數的乘積值會低於理論值。雷諾數對摩擦係數的乘積值，在摩擦係數增加的情況下，乘積值低於理論值的情形會越明顯。當莫迪圖表用於流體流動的情形時，粗糙度及雷諾數會同時影響到摩擦係數的大小，而當摩擦係數低於0.001時，對於微流體流動的影響並不明顯。

This rearech discussing about the relatiomnship between pressure drop and surface roughness. We found that it really exit the difference bteween micro scale & macro scale.
