    • BOT, Patrick (American Institute of Aeronautics and Astronautics (AIAA), 2019)
      The aim of this paper is to report and analyze experimental results on forces generated by a high-camber thin section with a sharp leading edge, namely a curved plate with 22.3% relative camber, and measurements of the ...
    • AUBIN, Nicolas; AUGIER, Benoit; DEPARDAY, Julien; SACHER, Matthieu (Ecole Navale, 2017)
      This work presents a wind tunnel experimental study of the effect of curling on the spinnaker aerodynamic performance. Four spinnakers combining two different panellings and sail materials are tested at different wind ...
    • BOT, Patrick; MARIA VIOLA, Ignazio; FLAY, Richard G.J.; BRETT, Jean-Sébastien (Ecole Navale, 2013)
      This paper describes an experiment that was carried out in the Twisted Flow Wind Tunnel at The University of Auckland to measure a detailed set of pressure distributions on a rigid 1/15th scale model of a modern asymmetric ...
    • FLAY, Richard G.J.; PIARD, A; BOT, Patrick (2017)
      While the aerodynamics of upwind sails are relatively well understood, flows past downwind sails are still very challenging. Indeed, downwind sails which can be considered as highly cambered thin wing profiles, are well ...
    • LE GUELLEC, Malo; AMICE, Yann (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 ...
    • SACHER, Matthieu; DURAND, Mathieu; BERRINI, E; HAUVILLE, Frédéric; DUVIGNEAU, R; LE MAITRE, O; ASTOLFI, Jacques André (2017)
      This paper investigates the use of constrained surrogate models to solve the multi-design optimization problem of a flexible hydrofoil. The surrogate-based optimization (EGO) substitutes the complex objective function of ...
    • DURAND, Mathieu; HAUVILLE, Frédéric; BOT, Patrick; AUGIER, Benoit; ROUX, Y; LEROYER, Alban; VISONNEAU, Michel (Royal Institution of Naval Architects, 2010)
      Modelling the wind, sail and rig interactions on a sailing yacht is a complex subject, because the quality of simulation depends on the accuracy of both structural and fluid simulations which strongly interact. Moreover, ...
