    • Discontinuity of lift on a hydrofoil in reversed flow for tidal turbine Application 
      Article dans une revue avec comité de lecture
      MARCHAND, Jean-Baptiste; ccASTOLFI, Jacques Andre; ccBOT, Patrick (Elsevier, 2017)
      This work presents an experimental investigation of a hydrofoil in reversed flow configuration in the context of marine current turbine development. Experiments consist in hydrodynamic force measurements and PIV flow ...
    • Fluid Structure Interaction of Yacht Sails in the Unsteady Regime 
      Chapitre d'ouvrage scientifique
      AUGIER, Benoit; ccBOT, Patrick; ccHAUVILLE, Frederic; DURAND, Mathieu (Editions de l'Ecole Polytechnique, 2013)
      The dynamic Fluid Structure Interaction (FSI) of yacht sails submitted to a harmonic pitching motion is numerically investigated to address both issues of aerodynamic unsteadiness and structural deformation. The model ...
    • Modal Analysis of Pressures on a Full-Scale Spinnaker 
      Article dans une revue avec comité de lecture
      DEPARDAY, Julien; ccBOT, Patrick; ccHAUVILLE, Frederic; AUGIER, Benoit; RABAUD, Marc; MOTTA, Dario; LE PELLEY, David (The Society of Naval Architects and Marine Engineers, 2017)
      While sailing offwind, the trimmer typically adjusts the downwind sail “on the verge of luffing”, occasionally letting the luff of the sail flap. Due to the unsteadiness of the spinnaker itself, maintaining the luff on the ...
    • Wind tunnel investigation of dynamic trimming on upwind sail aerodynamics 
      Article dans une revue avec comité de lecture
      AUBIN, Nicolas; AUGIER, Benoit; ccBOT, Patrick; ccHAUVILLE, Frederic; SACHER, Matthieu; FLAY, Richard G.J. (The Society of Naval Architects and Marine Engineers, 2017)
      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 ( AW = 60°) unheeled ...
    • Performance enhancement of downwind sails due to leading edge flapping: A wind tunnel investigation 
      Article dans une revue avec comité de lecture
      AUBIN, Nicolas; AUGIER, Benoit; DEPARDAY, Julien; SACHER, Matthieu; ccBOT, Patrick (Elsevier, 2018)
      This work presents a wind tunnel experimental study on the effect of the leading edge flapping on the aerodynamic performance of a spinnaker. Four J80-class spinnaker models, combining two different assembling structures ...
    • Transducteur adapté à la génération de forces en fonction de la vitesse d'écoulement d'un fluide 
      Brevet
      ccBOT, Patrick (Organisation Mondiale de la Propriété Intellectuelle, 2017)
      L’invention concerne un dispositif détecteur d’une vitesse seuil de déplacement d’un fluide, le dispositif détecteur comprenant un transducteur et configuré pour exercer une première force non nulle dans une première ...
    • Design of a spatial database to analyze the forms and responsiveness of an urban environment using an ontological approach 
      Article dans une revue avec comité de lecture
      SILAVI, Tolue; HAKIMPOUR, Farshad; ccCLARAMUNT, Christophe; NOURIAN, Farshad (Elsevier, 2016)
      This paper introduces a spatial database and ontology-enabled framework that models and operationalizes the relation between urban forms and their responsiveness to the needs of its user. The objective is to offer a framework ...
