On the efficiency of fish like swimming
ORAL
Abstract
The aim of this talk is to present a parametric study of underwater locomotion via numerical simulations. The Navier-Stokes equations are discretized onto a cartesian mesh and the interface between the fluid and the fish is computed using an immersed boundary method. The lagrangian motion of the swimmer is computed from the Newton's laws. We present results showing how the swimming efficiency is influenced by the reynolds number and the swimming law.
