In this work the flow field around an America's cup class Keel is studied by the numerical solution of the Reynolds Averaged Navier-Stokes equations (RANSE). An analysis is carried out in order to assess the efficiency of the winglet in reducing the induced resistance of the keel. Velocity, pressure and vorticity fields have been analyzed to improve the understanding of the flow field around such a peculiar hydrodynamics appendage. Velocity and pressure fields, as well as global loads for the simulations with and without winglets configurations are compared. Comparison with available experiments is made.

Abstract
In this work the flow field around an America's cup class Keel is studied by the numerical solution of the Reynolds Averaged Navier-Stokes equations (RANSE). An analysis is carried out in order to assess the efficiency of the winglet in reducing the induced resistance of the keel. Velocity, pressure and vorticity fields have been analyzed to improve the understanding of the flow field around such a peculiar hydrodynamics appendage. Velocity and pressure fields, as well as global loads for the simulations with and without winglets configurations are compared. Comparison with available experiments is made.File in questo prodotto:
