課程概述

體力學為熱流方面的基礎科目之一,在日常生活中的諸多流體現象或者工業應用上的流體機械、旋轉機械、流體工程等,均與流體力學息息相關。流體力學基本上可分為流體靜力學及流體動力學兩個大方向。靜力學探討流體為靜止或等速運動下之受力情形,動力學則探討流體粒子間有相對運動時之流場之分佈。動力學可分為穩流及非穩流兩類; 若依流體特性來分,黏性與非黏性流體亦為探討對象;另外,壓縮性與不可壓縮性流體之應用亦為重點之一。由於流體力學涵蓋範圍很廣,因此本課程將著重於流體力學的基本理論、流體工程問題之分析技巧以及物理現象的解釋,希望透過授課的內容、上課時討論以及習題的練習,使同學在修完本課程後,在未來遇到流體工程問題時,能懂得去分析、解決,並且對流體力學及在工業上的應用有更深入的了解。
