    • 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 ...
    • Analysis of Cavitation Instabilities in a Four-Blade Inducer 
      Article dans une revue avec comité de lecture
      ccCOUTIER-DELGOSHA, Olivier; ccDAZIN, Antoine; CAIGNAERT, Guy; BOIS, Gérard (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 ...
    • 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. ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
