Communication avec acte(2016)An experiment was performed in the Yacht Research Unit’s Twisted Flow Wind Tunnel (University of Auckland) to test the effect of dynamic trimming on three IMOCA 60 inspired mainsail models in an upwind (AWA = 60 ) unheeled ...
-
Communication avec acte(2015)A numerical comparison between two FSI models, based on inviscid and viscous flow solvers, is presented in this paper. The differences between aerodynamic coefficients, sail flying shape and pressures computed by both FSI ...
-
Article dans une revue avec comité de lecture(Elsevier, 2017)This paper investigates the use of Gaussian processes to solve sail trimming optimization problems. The Gaussian process, used to model the dependence of the performance with the trimming parameters, is constructed from a ...
-
Communication avec acte(Ecole Navale, 2013)A numerical investigation of the dynamic Fluid Structure Interaction (FSI) of a yacht sail plan submitted to harmonic pitching is presented to analyse the effects of motion simplifications and rigging adjustments on ...
-
Communication avec acte(Ecole Navale, 2013)Gennakers are lightweight and flexible sails, used for downwind sailing configurations. Qualities sought for this kind of sail are propulsive force and dynamic stability. To simulate accurately the flow around such a sail, ...

Communication avec acte(Ecole Navale, 2013)To have a prior accurate knowledge of the local wind currents on a water body is of crucial importance for the performance of the sailing team. In the recent years, Computational Fluid Dynamics (CFD) has proven itself a ...
