| 英文摘要 | Koi carps frequently swim in burst-and-coast style, which consists of a burst phase and a coast phase. we quantify the swimming kinematics and the flow patterns generated by the carps in burst-and-coast swimming. in the burst phase, the carps burst in two modes: in the first, the tail beats for at least one cycle (multiple tail-beat mode); in the second, the tail beats for only a half-cycle (half tail-beat mode). the carp generates a vortex ring in each half-cycle beat. the vortex rings generated during bursting in multiple tail-beat mode form a linked chain, but only one vortex ring is generated in half tail-beat mode. the wake morphologies, such as momentum angle and jet angle, also show much difference between the two modes. in the burst phase, the kinematic data and the impulse obtained from the wake are linked to obtain the drag coefficient (c-d,c-tnurst approximate to 0.242). in the coast phase, drag coefficient (c-d,c-coast approximate to 0.060) is estimated from swimming speed deceleration. our estimation suggests that nearly 45% of energy is saved when burst-and-coast swimming is used by the koi carps compared with steady swimming at the same mean speed. |
