    • Analysis of Cavitation Instabilities in a Four-Blade Inducer 
      Article dans une revue avec comité de lecture
      CAIGNAERT, Guy; BOIS, Gérard; ccDAZIN, Antoine; ccCOUTIER-DELGOSHA, Olivier (HPC - Hindawi Publishing Corporation, 2012)
      The cavitating behavior of a four-blade inducer tested in the LML laboratory large test facility is considered in the present paper. Experimental investigations based on unsteady pressure measurements and records from a ...
    • 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 VELOCITY PIV MEASUREMENTS AND 3D NUMERICAL CALCULATION COMPATISONS INSIDE THE IMPELLER OF A RADIAL PUMP MODEL 
      Communication avec acte
      CAVAZZINI, Giovanna; DUPONT, Patrick; PAVESI, Giorgio; BOIS, Gérard; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (2013)
      PIV measurements were performed at mid hub section inside the impeller of a vaned diffuser pump model working with air. Several previous papers have already presented part of impeller flow characteristics mainly for vaneless ...
    • 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 ...
    • Experimental and Numerical Investigation of Unforced unsteadiness in a Vaneless Radial Diffuser 
      Communication avec acte
      PAVESI, Giorgio; CAVAZZINI, Giovanna; CAIGNAERT, Guy; BOIS, Gérard; ARDIZZON, Guido; ccDAZIN, Antoine (EUROTURBO, 2011)
      The paper reports combined experimental and numerical investigations of unforced un- steadiness in a vaneless radial diffuser. Experimental data were obtained within the diffuser using stereoscopic time resolved Particle ...
    • 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, ...
