    • 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 ...
    • 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 ...
    • 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 ...
    • Analysis of Unsteadinesses in a Vaned Diffuser of Centrifugal Machinery. 
      Communication avec acte
      CHERDIEU, Patrick; DUPONT, Patrick; ROUSSETTE, Olivier; BOIS, Gérard; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (2013)
      The aim of this article is to present experimental results obtained on a fan composed of a radial impeller matched with a vaned diffuser. There is no volute downstream to the diffuser. Consequently the diffuser outlet is ...
    • 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 ...
