Paper presented at the 9th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Malta, 16-18 July, 2012.
The aim of this work is to identify experimentally the
features of the lateral flow in a cross-section slice of an
elongated body during locomotion. We use an experimen-
tal approach in the context of the undulatory swimming
of an elongated body. For that, two kinematic parameters
of the fish’s body are taking into account, the body’s cur-
vature and the cross-section diameter. We examine the
lateral flow field for different elliptical cylinder-shape, and
we perform the experiments using particle image velocime-
try (PIV) technique.
