Proceedings in flow modelling in the surroundings of the end part of a trawl.

Abstract : This paper is devoted to the presentation of modelling procedures and of numerical simulations of the flow in the surroundings of the end part of a trawl, where fish are caught. We present first the hydrodynamical data collected in November 2004 at the IFREMER tank of Boulogne-sur-Mer around and inside an axisymmetric rigid net model. Then we show the use of averaged Navier-Stokes/Brinkman equations with an eddy viscosity coupled with an equation for the turbulent kinetic energy (TKE) (RANS type model of order one) as for a turbulent fluid model. Finally, we test this last model by comparing the numerical results obtained with the code that we have written in Freefem++ and the experimental data available.
