    • KGmax curves associated with second generation intact stability criteria for different types of ships 
      Article dans une revue avec comité de lecture
      GRINNAERT, François; BILLARD, Jean-YVes; LAURENS, Jean-Marc (Springer Verlag (Germany), 2016)
      Currently, second generation intact stability criteria are being developed and evaluated by the International Maritime Organization (IMO). In this paper, we briefly present levels 1 and 2 assessment methods for the criteria ...
    • Full-scale flying shape measurement of offwind yacht sails with photogrammetry 
      Article dans une revue avec comité de lecture
      DEPARDAY, Julien; ccBOT, Patrick; ccHAUVILLE, Frederic; AUGIER, Benoit; RABAUD, Marc (Elsevier, 2016)
      Yacht downwind sails are complex to study due to their non-developable shape with high camber and massively detached flow around thin and flexible membranes. Numerical simulations can now simulate this strong fluid-structure ...
    • A Simulation Model for the Evaluation of the Electrical Power Potential Harnessed by a Marine Current Turbine 
      Article dans une revue avec comité de lecture
      BEN ELGHALI, Seif Eddine; BALME, Rémi; LE SAUX, Karine; BENBOUZID, Mohamed; CHARPENTIER, Jean-Frederic; ccHAUVILLE, Frederic (Institute of Electrical and Electronics Engineers, 2007)
      This paper deals with the development of a Matlab–Simulink model of a marine current turbine system through the modeling of the resource and the rotor. The simulation model has two purposes: performances and dynamic loads ...
    • Thickness effect of NACA foils on hydrodynamic global parameters, boundary layer states and stall establishment 
      Article dans une revue avec comité de lecture
      ccSARRAF, Christophe; DJERIDI, Henda; PROTHIN, Sébastien; BILLARD, Jean-Yves (Elsevier, 2010)
      The present study investigates experimentally the hydrodynamic behavior of 2D NACA (15, 25, 35%) symmetric hydrofoils at Reynolds number 0.5 106 . A particular attention is paid on the hysteretic behavior at static stall ...
    • Open ocean regimes of relative dispersion 
      Article dans une revue avec comité de lecture
      OLLITRAULT, Michel; GABILLET, Céline; COLIN DE VERDIERE, Alain (Cambridge University Press (CUP), 2005)
      As two fluid particles separate in time, the entire spectrum of eddy motions is being sampled from the smallest to the largest scales. In large-scale geophysical systems for which the Earth rotation is important, it has ...
    • Analysis of the flow pattern modifications in a bubbly Couette-Taylor flow 
      Article dans une revue avec comité de lecture
      MEHEL, Amine; GABILLET, Céline; DJERIDI, Henda (American Institute of Physics, 2007)
      The aim of this Brief Communication is to discuss the bubble effect on the Couette-Taylor flow patterns in the transition from laminar to turbulent flow, especially in the weakly turbulent regime. It is shown that bubble ...
    • Semi-analytical study of 3 kinds of axial flux PM actuator 
      Article dans une revue avec comité de lecture
      JENNANE, J; FADLI, N.; CHARPENTIER, Jean-Frederic; RIOS QUESADA, Javier (IOS Press, 2004)
      This paper deals with the study of discoidal Permanent Magnet machines using a method of field calculation based on the magnetic charges theory. This fast calculation method enables a systematic study of these devices. The ...
