摘要

非牛頓流體種類繁多，如含泥水流、混合懸浮液體、泥漿等。這些流體流動行為相當複雜，已脫離牛頓流體之範疇。故需要利用實驗找出新的流變關係式及流變參數，進而推求非牛頓流體之流動特性，作為研究、發展、應用之用。
楊(2003)研究石門水庫淤泥之流變特性，在不同濃度下以冪定理流體模式分析其流變參數稠度係數m、流動指數n。本文利用其不同濃度之實驗，所分析淤泥流變參數m、n，代入含泥流體流動主要損失公式，推求出實際的水頭主要損失；並利用呂(2004)之有關流動次要損失之損失係數實驗結果，推求實際之次要損失，最後利用能量方程式推求現場抽泥濃度之幫浦效率。本研究發現輸送含泥流對於現場抽泥濃度之幫浦效率約30％左右。

There are many kinds of Non-Newtonian fluids, such as the fluids of soil-water mixture, suspended liquid of mixture, slurry etc. The flowing behaviors of these fluids are very complicated, because they do not belong to the categories of the Newtonian fluids. So one needs to make use of experiments to find out their rheological relations and rheological parameters, therefore ,their flowing behaviors of Non-Newtonian fluids can be derived and be used as the references for studies, developments and applications.
Yang(2003) investigated the sludge of Shi-Men reservoir and determined the rheological parameters m, n with Power law model in his experiments of different concentration. This study determined sludge actual major loss by using his rheological parameters m, n in the experiment of different concentration , and formula for the major loss. The actual minor losses were calculated by using the minor loss coefficient from the results of Lu’s(2004) experiment. Finally, the study determined the efficiency of pumps for the concentration of site. The study found the efficiency of pumps in the site is about 30 %.
