    • Etude numérique instationnaire d'une micro-éolienne à axe vertical 
      Communication sans acte
      ccBAYEUL-LAINÉ, Annie-Claude; BOIS, Gérard; ccSIMONET, Sophie (2010)
      Bien que les éoliennes soient une forme très ancienne d’exploitation du vent, ces dernières quarante dernières années ont vu leur évolution et un développement important de leur conception dans le cadre du développement ...
    • Unsteady simulation of flow in micro vertical axis wind turbine 
      Communication avec acte
      BOIS, Gérard; ccBAYEUL-LAINÉ, Annie-Claude (2010)
      Though wind turbines and windmills have been used for centuries, the application of aerodynamics technology to improve reliability and reduce costs of wind-generated energy has only been pursued in earnest for the past 40 ...
    • Numerical study of flow stream in a mini VAWT with relative rotating blades 
      Communication avec acte
      DOCKTER, Aurore; BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (2011)
      Today, wind energy is mainly used to generate electricity and more and more with a renewable energy source character. Power production from wind turbines is affected by several conditions like wind speed, turbine speed, ...
    • NUMERICAL AND EXPERIMENTAL INVESTIGATIONS IN A VANED DIFFUSER OF SHF IMPELLER: FLUID LEAKAGE EFFECT 
      Communication avec acte
      DUPONT, Patrick; CAVAZZINI, Giovanna; CHERDIEU, Patrick; BOIS, Gérard; ROUSSETTE, Olivier; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (2013)
      The paper presents the analysis of the performance and the internal flow behaviour in the vaned diffuser of a radial flow pump using PIV technique, pressure probe traverses and numerical simulations. PIV measurements have ...
    • Numerical Simulation of Flow Field Formed in Water Pump-Sump 
      Communication avec acte
      ISSA, Abir; BOIS, Gérard; ccBAYEUL-LAINÉ, Annie-Claude (IAHR - The International Association for Hydro-Environment Engineering and Research, 2008)
      Two fundamental types of flow problems besetting water intakes are swirling flow problems in the pump sump and sediment problems at entrance or within intakes. Both problems reduce intake performance and lead to increased ...
    • VELOCITY MEASUREMENTS IN CAVITATING FLOWS USING FAST X-RAY IMAGING 
      Communication sans acte
      KHLIFA, Ilyass; FUZIER, Sylvie; HOCEVAR, Marko; VABRE, Alexandre; FEZZAA, Kamel; ccCOUTIER-DELGOSHA, Olivier (2013)
      A promising method to measure velocity fields in complex two-phase flows such us cavitating flows is presented. Dynamics of the liquid phase and the bubbles are both investigated. The measurements are based on ultra fast ...
    • Modeling of Hydro-Pneumatic Energy Storage Using Pump Turbines 
      Communication avec acte
      ORTEGO, Egoï; ccDAZIN, Antoine; CAIGNAERT, Guy; COLAS, Frédéric; ccCOUTIER-DELGOSHA, Olivier (SHF - Société Hydrotechnique de France, 2011)
      Modelling of a hydro-pneumatic energy storage system is presented in this paper. Hydro pneumatic storage aims to combine the good efficiency of hydraulic energy conversion and the space flexibility of pneumatic storage. ...
