Optimal shapes for anguilliform swimmers at intermediate Reynolds numbers
We investigate the optimal morphologies for fast and efficient anguilliform swimmers at intermediate Reynolds numbers, by combining an evolution strategy with threedimensional viscous vortex methods. We show that anguilliform swimmer shapes enable the trapping and subsequent acceleration of regions of fluid transported along the entire body by the midline travelling wave. A sensitivity analysis...
متن کاملAn elastic rod model for anguilliform swimming.
We develop a model for anguilliform (eel-like) swimming as an elastic rod actuated via time-dependent intrinsic curvature and subject to hydrodynamic drag forces, the latter as proposed by Taylor (in Proc Roy Proc Lond A 214:158-183, 1952). We employ a eometrically exact theory and discretize the resulting nonlinear partial differential evolution both to perform numerical simulations, and to co...
متن کاملForces on the Tail Surface of Swimming Fish: Thrust, Drag and Acceleration in Bluefish (pomatomus Saltatrix)
1. Pressures on the right and left sides of the tails of swimming bluefish were measured and found to have a range of +5*9 to —5-9 cm H20. The pressures were resolved into their forward and lateral vectorial components of force to allow calculation of forward and lateral force and power at speeds ranging from 0-26 to 0-87 m/s. 2. The peak to peak changes in force of acceleration of the body, me...
متن کاملKinematics of swimming in two burrowing anguilliform fishes.
Anguilliform or eel-like fishes are typically bottom dwellers, some of which are specialized burrowers. Although specializations for burrowing are predicted to affect the kinematics of swimming, it remains unknown to what extent this is actually the case. Here we examine swimming kinematics and efficiency of two burrowing anguilliform species, Pisodonophis boro and Heteroconger hassi, with diff...
متن کاملSwimming in needlefish (Belonidae): anguilliform locomotion with fins.
The Atlantic needlefish (Strongylura marina) is a unique anguilliform swimmer in that it possesses prominent fins, lives in coastal surface-waters, and can propel itself across the surface of the water to escape predators. In a laboratory flow tank, steadily swimming needlefish perform a speed-dependent suite of behaviors while maintaining at least a half wavelength of undulation on the body at...
