The features of the lateral flow in the cross-section slice of an elongated body : experimental approach

Abstract

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.
