    • 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 ...
    • INVESTIGATIONS IN A VANED DIFFUSER OF SHF IMPELLER 
      Communication avec acte
      DUPONT, Patrick; CAVAZZINI, Giovanna; CHERDIEU, Patrick; BOIS, Gérard; ROUSSETTE, Olivier; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (2013)
      The paper presents the numerical and experimental analysis of performance and internal flow behaviour in the vaned diffuser of a radial flow pump (Fig. 1) using PIV technique (Fig. 2), pressure probe traverses and numerical ...
    • 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 ...
    • 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 ...
    • Numerical study of cavitating flow inside a flush valve 
      Article dans une revue avec comité de lecture
      DUTHEIL, Daniel; CAIGNAERT, Guy; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (Elsevier, 2011)
      In water supply installations, noise pollution often occurs. As a basic component of a system, a flush valve may frequently be a source of noise and vibration generated by cavitation or high turbulence levels. During valve ...
