    • 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 ...
    • 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 ...
    • Modeling of Hydro-Pneumatic Energy Storage Using Pump Turbines 
      Communication avec acte
      ORTEGO, Egoï; CAIGNAERT, Guy; COLAS, Frédéric; ccDAZIN, Antoine; 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. ...
    • 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 ...
    • 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 ...
    • Spectral analysis of unsteady flow simulation in a small VAWT 
      Communication avec acte
      BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (2012)
      The vertical axis wind turbine studied in this paper combine two rotations: one rotating movement of each blade around its own axis and one rotating movement around turbine’s axis. The aim of this paper is to analyse the ...
    • Numerical simulation of flow field in water-pump sump and inlet suction pipe 
      Article dans une revue avec comité de lecture
      ccBAYEUL-LAINÉ, Annie-Claude; BOIS, Gérard; ISSA, Abir (IOP - Institute of Physics, 2010)
      There are several important considerations in the design of a suction supply sump. It is imperative that the amount of turbulence and entrained air be kept to a minimum. Free aircore vortex occurring at a water-intake pipe ...
