碩士 / 國立臺灣大學 / 應用力學研究所 / 104 / 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.
