    • Influence of the Blade Number on Inducer Cavitating Behavior 
      Article dans une revue avec comité de lecture
      CAIGNAERT, Guy; BOIS, Gérard; LEROUX, Jean-Baptiste; ccCOUTIER-DELGOSHA, Olivier (American Society of Mechanical Engineers, 2012)
      Effects of the blade number on the performance of a rocket engine turbopump inducer are investigated in the present paper. For that purpose, two inducers characterized by three blades and five blades, respectively, were ...
    • 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 ...
    • Data reduction problems using a 3 holes directional pressure probe to investigate mean flow characteristics in the vaneless gap between impeller and diffuser radial pump 
      Communication avec acte
      CHERDIEU, Patrick; DUPONT, Patrick; BOIS, Gérard; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (6 th international conference on pimps and fans with compressors and wind turbines, 2013)
      Among several different measurement techniques that have been already performed and presented in a radial impeller pump model including PIV, a directional pressure probe has been used to obtain mean velocity field and ...
    • Transient behavior of a radial vaneless diffuser 
      Communication avec acte
      DUPONT, Patrick; CAIGNAERT, Guy; BOIS, Gérard; ccDAZIN, Antoine (ASME, 2011)
      The paper refers to the behavior of a radial flow pump vaneless diffuser during a starting period. Results obtained with a 1D numerical model are compared with some new experimental data which have been obtained using 2D/3C ...
    • 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
      ccBAYEUL-LAINÉ, Annie-Claude; ccSIMONET, Sophie; BOIS, Gérard; ISSA, Abir (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. ...
    • Unsteady flow field in a mini VAWT with relative rotation blades: analysis of temporal results 
      Communication sans acte
      BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (6 th International Conference of Pumps and Fans with compressors and wind turbines, 2013)
      The present wind turbine is a small one which can be used on roofs or in gardens. This turbine has a vertical axis. Each turbine blade combines a rotating movement around its own axis and around the main rotor axis. Due ...
    • Numerical study of the influence of Geometrical Parameters on flow in water Pump-Sump 
      Communication avec acte
      ISSA, Abir; BOIS, Gérard; ccBAYEUL-LAINÉ, Annie-Claude (CMFF - Conference on Modelling Fluid Flow, 2009)
      Water for irrigation, domestic and industrial supply as well for some power generation is normally drawn directly from rivers or from reservoir through sumps. The flow at the pump section sump may have large effects on the ...
