    • 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. ...
    • VAWT with controlled blades : influence of wake of one turbine on power coefficient on the next turbine 
      Communication avec acte
      BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (IC-EpsMsO, 2013)
      Power production from wind turbines is affected by several conditions like wind speed, turbine speed, turbine design, turbulence, changes of wind direct ion, wake of previous turbines. These conditions are not always optimal ...
    • Post-processing methods of PIV instantaneous flow fields for unsteady flows in turbomachines 
      Chapitre d'ouvrage scientifique
      CAVAZZINI, Giovanna; PAVESI, Giorgio; DUPONT, Patrick; BOIS, Gérard; ccDAZIN, Antoine (Intech, 2012)
      The Particle Image Velocimetry is undoubtedly one of the most important technique in Fluid-dynamics since it allows to obtain a direct and instantaneous visualization of the flow field in a non-intrusive way. This innovative ...
    • The importance of the knowledge of flow stream in water sump pump 
      Communication avec acte
      ISSA, Abir; BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (2013)
      Numerous different experimental and numerical methods have been developed and are already improved in order to get rather good flow descriptions inside pump components. These calculations are generally realized assuming ...
    • Development of algorithm based on the fractional time step for the simulation of cavitation. 
      Communication sans acte
      CHEBLI, Rezki; AUDEBERT, Bruno; ccCOUTIER-DELGOSHA, Olivier (2013)
      Cavitation is one of the most demanding physical phenomena influencing the performance of hydraulic machines. It is therefore important to predict correctly its inception and development appearance, and quantify the ...
