| dc.description.abstract | 近年來有許多學者投入水下載具的開發，而在追求高效率的推進機制時，大自然中各種海洋生物其高效的泳動模式即為很好的借鏡對象。
對於魚類泳動行為的相關研究大致分為(1)以活體生物作為研究對象，觀察其行為模式(2)以仿生機構取代活體，量測機構在流場中的受力情形。本文之研究屬於後者，以兩片撓性材質所作之翼板作為仿生魚尾，模仿兩魚並排游動之情形，包括兩魚尾做同相及具一定相差的運動，探討其在流場中之受力情形及推進效率，並配合流場顯影技術，使用粒子影像測速法計算出流場的渦度。 | zh_TW |
| dc.description.abstract | Last few years people focus on developing AUV（Autonomous Underwater Vehicle）. In the pursuit of high-efficiency propulsion mechanism, the nature of various marine organisms and its highly efficient mobility mode is a good learning object.
Related researches for the swimming behavior of fish can roughly divided into two types:(1) Using living organisms for the study and observe their behavior patterns.(2)Using biomimetic mechanism to replace living organisms and measure its susceptive force in the flow field. This research belongs to the latter type. Using two foils made of flexible material to represent fish tails. Imitating the situation that when two fishes swimming side by side. The swimming mode contains in-phase and out-of-phase, and also discuss their susceptive force and propulsion efficiency. In the final chapter we use particle image velocimetry (PIV) method to calculate the vorticity in the flow field. | en |
