シーラカンス胸鰭の受動的撓みがその流体力学的性能に及ぼす影響

Open water characteristics are measured in a circulating water channel with four model pectoral fins with different bending stiffness of Coelacanth. Open efficiencies reach highest value in the range of Strouhal numbers between 0.2 and 0.4 and maximum value of open efficiency increases with reducing bending stiffenss.
