摘要

Undulatory flexible bodies can harvest energy from fluid flow under certain motion parameters. In order to reveal how schooling patterns affect the energy absorption efficiency of undulatory fishlike airfoils, several parameters have been considered, such as spacing and phase differences between the two airfoils. The object of this study is to employ NACA0012 airfoil as a two-dimensional simplified model, by means of numerical simulation, to investigate the influence of spacing and phase differences on energy harvest of double undulatory airfoils in different patterns. For convenience of analysis, the efficiency of energy harvest, also called energy absorption efficiency, has been calculated separately for each of the double airfoils. The results indicate that energy absorption efficiency, whether in a tandem or staggered pattern, will change significantly, compared with that in a single airfoil.(c) 2021 Published by Elsevier Ltd.
