3944 ステレオPIVによる屈曲型魚周りの微細渦構造の可視化(G05-5 生物流体,G05 流体工学)  [in Japanese] 3944 Stereoscopic PIV Analysis of Detailed Vortices around Bending Body of Anguilliform Fish  [in Japanese]

The propulsion method of the aquatic life is a result of optimization by evolution. Research of the propulsion method is useful for the design of robot that operates efficiently, for example swimming -robot etc. This study is about a loach that swims bending whole body. Our purpose of research is to clarify its swimming mechanism through flow field analysis. We analyzed the three -dimensional flow field around the loach using stereo-PIV. As a result, we captured three-dimensional flow field and vortex structure around the loach.
