  • 本次研究以計算流體力學為工具,對T型管微混合器進行數值實驗,探討在T型管主流道內加入之橫條檔板對混合效率的影響,並以田口方法設計橫條擋板的結構參數,利用直交表搭配因子反應表找出對混合效率有利的參數趨勢,進而找出高混合效率之設計參數。

    In this research numerial simulation of the flow field of T-tube micromixer are performed using a commercial CFD software. The effect of oblique crossbar structure on mixing efficiency of the micromixer.Taguchi method has been used to design the geometric parameter of the oblique crossbar. Using the orthogonal array and response table to find the advantage of mixing efficiency,then identify the geometric parameter with good mixing efficiency.
