Última Time-Resolved PIV investigations of the flow field around cod-end net structures 5 Bouhoubeiny, Elkhadim; Germain, Gregory; Druault, Philippe. Flow field measurements past a fixed rigid cod-end structure and past a porous fishing net structure are conducted using Time-Resolved PIV method. The rigid cod-end is first used to characterize finely the wake flow. Proper Orthogonal Decomposition (POD) is then applied in order to extract the large scale energetic vortices of the flow from the measured velocity field. It is then observed that the first POD modes are associated to the Karman's type flow structure of vortex shedding. It is shown that the characteristics of the wake flow behind the rigid cod-end flow configuration compare quite well with previous ones obtained from bluff cylinder or sphere wake analyzes. Second, PIV measurements are performed around a non-rigid bottom trawl which is free to... Tipo: Text Palavras-chave: Fishing gear; PIV measurements; Vortex shedding; Proper Orthogonal Decomposition.
