Optimal morphokinematics for undulatory swimmers at intermediate Reynolds numbers
Undulatory locomotion is an archetypal mode of propulsion for natural swimmers across scales. Undulatory swimmers convert transverse body oscillations into forward velocity by a complex interplay between their flexural movements, morphological features and the fluid environment. Natural evolution has produced a wide range of morphokinematic examples of undulatory swimmers that often serve as in...
متن کاملmorphokinematics for undulatory swimmers at intermediate Reynolds numbers
We noted in the main text the high Strouhal number corresponding to both our and Kern & Koumoutsakos (2006) optimal e cient swimmer's, and attributed this to the lower Reynolds number used in these computational works compared with the analyses in Triantafyllou et al. (1993); Taylor et al. (2003), consistent with Gazzola et al. (2014). However, both in Kern & Koumoutsakos (2006) and in the curr...
متن کاملOptimal 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 کاملControllability and time optimal control for low Reynolds numbers swimmers
Abstract. The aim of this paper is to tackle the self-propelling at low Reynolds number by using tools coming from control theory. More precisely we first address the controllability problem: ”Given two arbitrary positions, does it exist ”controls” such that the body can swim from one position to another, with null initial and final deformations?”. We consider a spherical object surrounded by a...
متن کاملThe hydrodynamics of locomotion at intermediate Reynolds numbers: undulatory swimming in ascidian larvae (Botrylloides sp.).
Understanding how the shape and motion of an aquatic animal affects the performance of swimming requires knowledge of the fluid forces that generate thrust and drag. These forces are poorly understood for the large diversity of animals that swim at Reynolds numbers (Re) between 10(0) and 10(2). We experimentally tested quasi-steady and unsteady blade-element models of the hydrodynamics of undul...
