    • FSI investigation on stability of downwind sails with an automatic dynamic trimming 
      Article dans une revue avec comité de lecture
      DURAND, Mathieu; LEROYER, Alban; LOTHODE, Corentin; ccHAUVILLE, Frederic; VISONNEAU, Michel; FLOCH, Ronan; GUILLAUME, Laurent (Elsevier, 2014)
      Gennakers are lightweight and flexible sails, used for downwind sailing configurations. Qualities sought for this kind of sail are propulsive force and dynamic stability. To simulate accurately the flow surrounding a sail, ...
    • Local and global spatio-temporal entropy indices based on distance- ratios and co-occurrences distributions 
      Article dans une revue avec comité de lecture
      LEIBOVICI, Didier G.; ccCLARAMUNT, Christophe; LE GUYADER, Damien; ccBROSSET, David (Taylor & Francis, 2014)
      When it comes to characterize the distribution of ‘things’ observed spatially and identified by their geometries and attributes, the Shannon entropy has been widely used in different domains such as ecology, regional ...
    • Modélisation couplée multiphysique d'une hydrolienne RIM-DRIVEN 
      Article dans une revue avec comité de lecture
      DROUEN, Laurent; CHARPENTIER, Jean-Frederic; ccHAUVILLE, Frederic; ccASTOLFI, Jacques Andre; ccSEMAIL, Eric; ccCLENET, Stephane (EDP Sciences, 2015)
      Le travail présenté concerne le développement d’une méthodologie de conception de systèmes hydroliens innovants de type RIM‑DRIVEN pour la récupération de l’énergie des courants de marée. L’originalité d’un système RIM‑DRIVEN ...
    • Exploring Geographical Crowd’s Emotions with Twitter 
      Article dans une revue avec comité de lecture
      WAKAMIYA, Shoko; BELOUAER, Lamia; ccBROSSET, David; KAWAI, Yukiko; ccCLARAMUNT, Christophe; SUMIYA, Kazutoshi (2015)
      The research introduced in this paper develops a semantic model whose objective is to analyze the geographical and emotion-based distribution of tweets at a large country scale. The approach extracts and categorizes tweets ...
    • High-Order Sliding Mode Control of a Marine Current Turbine Driven Permanent Magnet Synchronous Generator 
      Communication avec acte
      BEN ELGHALI, Seif Eddine; BENBOUZID, Mohamed; CHARPENTIER, Jean-Frederic; AHMED-ALI, Tarek; MUNTEANU, Iulian (IEEE, 2009)
      This paper deals with the speed control of a Permanent Magnet Synchronous Generator (PMSG)-based Marine Current Turbine (MCT). Indeed, to increase the generated power and therefore the efficiency of an MCT, a nonlinear ...
    • Effect of bubble’s arrangement on the viscous torque in bubbly Taylor- Couette flow 
      Article dans une revue avec comité de lecture
      NDONGO FOKOUA, Georges; GABILLET, Céline; AUBERT, Adrien; COLIN, Catherine (American Institute of Physics, 2015)
      An experimental investigation of the interactions between bubbles, coherent motion and viscous drag in a Taylor-Couette flow with the outer cylinder at rest is presented. The cylinder radii ratio η is 0.91. Bubbles are ...
    • Two-phase Couette–Taylor flow: Arrangement of the dispersed phase and effects on the flow structures 
      Article dans une revue avec comité de lecture
      DJERIDI, Henda; GABILLET, Céline; BILLARD, Jean-Yves (American Institute of Physics, 2004)
      This study investigates the mutual interactions between a continuous and a dispersed phase~noncondensable or condensable! in the well-known Couette–Taylor flow between two concentric cylinders at low Reynolds numbers, where ...
