摘要

本研究為分析於具有陣列桿件之移動平行頂板與底板間之黏性流體理論，流體速度以Poissin方程式展開，並以point-matching法求解之。結果顯示當流體與平板同方向移動時，f Re隨平板移動速度增加而降低。然而，當平板逆向運動，回流將發生於頂板與底板之間，且f Re值於較大的逆向平板速度之下將會提高。再者，局部流速、平均流速與流體流量的分佈受到平板移動與陣列桿件影響亦於文中詳細討論。

This study analyzes the viscous fluid flow between the moving top and bottom plates with arrayed rectangle rods. The fluid velocity is described using Poisson equations, and calculated using the point-matching method. The result shows that when the plates move forward, the fluid moves in the same direction, and that the f Re value decreases as the plate velocity increases. However, when the plates move backward, a backflow occurs between the top and bottom plates, and the f Re value is higher at larger negative plate velocity. As well as the local fluid velocity, the mean fluid velocity and volume flow rate as influenced by the moving plates and arrayed rods are discussed.
