Burst-and-coast, as a locomotion type in freely routine swimming of koi carps (Cyprinus carpio koi) was studied, using a novel integrated CFD method solving the body-fluid interaction problem. The numerical simulation was incorporated with the tracking experiment. The two burst modes, MT (Multiple Tail-beat) and HT (Half Tail-beat) were investigated. The body locomotion was predicted and the flow physics was visualized, both in good agreement with the corresponding experiments. The energy cost and several critical control mechanisms in burst-and-coast swimming of koi carps are explored. Results on the energetics show that, burst-and-coast swimming does not actually save energy comparing with steady swimming at the same average speed, in that frequently changing of speed leads to decrease of efficiency.
