本研究主要可以分成兩部份,首先以泛用計算流體力學軟體作為模擬分析的工具,計算葉片式發電機組內部之流場,瞭解水流通過葉片式發電機組時所產生的流速及壓力分布情形;另一方面,應用以數值模擬所得到的壓力場,計算得知其對葉片所造成的阻力、升力及力矩,藉由力矩的變化來判斷不同設計型式的葉片式發電機組,其葉片所能達到之擺幅大小,進而提出較可行的設計型式。研究結果顯示,在本文所提出之兩種雛形中,雛型B(以下稱Plan B)之正向力矩表現較雛型A(以下稱Plan A)強烈,plan A的葉片擺幅在0〜8度之間,而plan B的葉片擺幅在0〜16度之間,若以葉片擺幅來決定發電效率,則plan B為比較可行的設計。
The purpose of this study can be divided into two parts. First, internal flow fields of blade-turbine generation units are investigated by computational fluid dynamics simulation software. The principal objectives of this part are to determine the relation between the flow and pressure distribution function associated with different types of blade-turbine generation units. On the other hand, the numerical results are analyzed provide new insights into the resistance, lift and torque caused by the blade. Changes from moment are used to design different types of blade-turbine generation units. Two blade-turbine generation units are proposed in the present research. The results show the plan A swing in between 0 to 8 degrees and plan B swing in between 0 to 16 degrees. It is found the plan B provides more power generation efficiency than the plan A.
