    • Performance Improvement of a Darrieus Tidal Turbine with Active Variable Pitch 
      Article dans une revue avec comité de lecture
      DELAFIN, Pierre-Luc; DENISET, François; ccASTOLFI, Jacques Andre; ccHAUVILLE, Frederic (MDPI AG, 2021)
      Vertical axis turbines, also called Darrieus turbines, present interesting characteristics for offshore wind and tidal applications but suffer from vibrations and a lower efficiency than the more conventional horizontal ...
    • Knowledge-Based Recommendation for On-Demand Mapping: Application to Nautical Charts 
      Article dans une revue avec comité de lecture
      KOTEICH, Bilal; SAUX, Eric; LADDADA, Wissame (MDPI AG, 2021)
      Maps have long been seen as a single cartographic product for different uses, with the user having to adapt their interpretation to his or her own needs. On-demand mapping reverses this paradigm in that it is the map that ...
    • Development of an Experimental Blade-controlled Cycloidal Propeller 
      Communication avec acte
      FASSE, Guillaume; ccHAUVILLE, Frederic; GERMAIN, Gregory; ccASTOLFI, Jacques Andre; BECKER, Florent (AFM, 2019)
      As an interesting naval propulsion system, this paper presents the development of an experimental cycloidal propeller. Cross-flow propellers are characterized by the rotation of several blades around a vertical axis ...
    • Verification and validation for the cavitating flow around a NACA0015 hydrofoil 
      Communication avec acte
      PERALI, Paolo; ccHAUVILLE, Frederic; LEROYER, Alban; ccASTOLFI, Jacques Andre; VISONNEAU, Michel (2019)
      When cavitation occurs around hydrofoils it is the cause of noise radiation, vibration and erosion. Consequently numerical cavitation models have been developped and tested over the last decades (Schnerr and Sauer [1]). ...
    • 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 ...
    • High Froude Number Experimental Investigation of the 2 DOF Behavior of a Multihull Float in Head Waves 
      Article dans une revue avec comité de lecture
      KERDRAON, Paul; HOREL, Boris; ccBOT, Patrick; LETOURNEUR, Adrien; DAVID LE TOUZÉ, David (The Society of Naval Architects and Marine Engineers, 2021)
      Dynamic Velocity Prediction Programs are taking an increasingly prominent role in high performance yacht design, as they allow to deal with seakeeping abilities and stability issues. Their validation is however often ...
    • Development of a 6-DOF Dynamic Velocity Prediction Program for offshore racing yachts 
      Article dans une revue avec comité de lecture
      KERDRAON, Paul; HOREL, Boris; ccBOT, Patrick; LETOURNEUR, Adrien; LE TOUZÉ, David (Elsevier, 2020)
      Thanks to high lift-to-drag ratios, hydrofoils are of great interest for high-speed vessels. Modern sailing yachts fitted with foils have thus reached impressively high speeds on the water. But this hydrodynamic efficiency ...
