We present experimental data elucidating the effects of hydrodynamic coupling on the propulsive efficiency of an array of three oscillating hydrofoils. We simulate this system using an inviscid flow model; this model duplicates certain key features of our experimental data but fails to consider the effects of wake vortex generation and interaction. We present a qualitative model for the role played by wake vortex dynamics in the cooperative locomotion of fish schools, and derive a mathematical model in the form of a nonlinear control system describing the interaction of a single deformable body with a single nearby vortex. We present simulations based on the latter to illustrate the capture of vortices shed from one fish in a school by a second, trailing fish; vortex capture in this sense is the control problem central to cooperative swimming. |
