    • Numerical study of a sinusoidal transverse propeller 
      Communication avec acte
      FASSE, Guillaume; ccBAYEUL-LAINÉ, Annie-Claude; ccCOUTIER-DELGOSHA, Olivier; CURUTCHET, Arnaud; PAILLARD, Benoît; ccHAUVILLE, Frederic (2018)
      In order to obtain higher propulsion efficiency for marine transportation, the authors have numerically tested a novel trochoidal propeller using a sinusoidal blade pitch function. The main results presented here are the ...
    • Force Variations Related to Flow Pattern Changes Around a High-Camber Thin Wing 
      Article dans une revue avec comité de lecture
      ccBOT, Patrick (American Institute of Aeronautics and Astronautics, 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 ...
    • Stand-Alone Island Daily Power Management Using a Tidal Turbine Farm and an Ocean Compressed Air Energy Storage System 
      Article dans une revue avec comité de lecture
      SHENG, Lei; ZHOU, Zhibin; CHARPENTIER, Jean-Frederic; BENBOUZID, Mohamed (Elsevier, 2016)
      Due to the high predictability and the high energy density, marine tidal resource has become an area of increasing interest with various academic and industrial projects around the world. In fact, several Marine Current ...
    • To curl or not to curl : wind tunnel investigation of spinnaker performance 
      Communication avec acte
      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 ...
    • Remote blue whale call detection using a passive version of the stochastic matched filter paper 
      Communication avec acte
      BOUFFAUT, Léa; DREO, Richard; LABAT, Valérie; ccBOUDRAA, Abdel-Ouahab; BARRUOL, Guilhem (2017)
      More than 30 years after the institution of the moratorium on commercial whaling by the International Whaling Commission, one of the biggest challenges in whale monitoring, e.g. Antarctic Blue Whales (ABW), is assessing ...
    • Aerodynamics of a highly cambered circular arc aerofoil : experimental investigations 
      Communication avec acte
      FLAY, Richard G.J.; PIARD, Arthur; ccBOT, 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 ...
    • Wind tunnel investigation of dynamic trimming on upwind sail aerodynamics 
      Communication avec acte
      AUBIN, Nicolas; AUGIER, Benoit; SACHER, Matthieu; FLAY, Richard G.J.; ccBOT, Patrick; ccHAUVILLE, Frederic (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 ...
