    • 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. ...
    • Two-phase numerical study of the flow field formed in water pump sump: influence of air entrainment 
      Article dans une revue avec comité de lecture
      BOIS, Gérard; ISSA, Abir; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (IOP - Institute of Physics, 2012)
      In a pump sump it is imperative that the amount of non-homogenous flow and entrained air be kept to a minimum. Free air-core vortex occurring at a water-intake pipe is an important problem encountered in hydraulic engineering. ...
    • Numerical simulation of flow field in water-pump sump and inlet suction pipe 
      Article dans une revue avec comité de lecture
      BOIS, Gérard; ISSA, Abir; ccBAYEUL-LAINÉ, Annie-Claude (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 ...
    • Numerical simulation in vertical wind axis turbine with pitch controlled blades 
      Communication avec acte
      DOCKTER, Aurore; BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (2012)
      Wind energy is more and more used as a renewable energy source character. The present wind turbine is a small one which allows to be used on roofs or in gardens to light small areas like publicity boards, parking, roads ...
    • Comparaisons between numerical calculations and measurements in the vaned diffusor of SHF impeller 
      Communication avec acte
      DUPONT, Patrick; CHERDIEU, Patrick; BOIS, Gérard; ROUSSETTE, Olivier; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (2012)
      The paper presents analysis of the performance and the internal flow behaviour in the vaned diffusor of a radial flow pump using PIV technique and pressure probe traverses. PIV measurements have been performed at mid height ...
    • 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 ...
    • 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 ...
