    • Numerical simulation in vertical wind axis turbine with pitch controlled blades 
      Communication avec acte
      DOCKTER, Aurore; BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (2012)
      Wind energy is more and more used as a renewable energy source character. The present wind turbine is a small one which allows to be used on roofs or in gardens to light small areas like publicity boards, parking, roads ...
    • VELOCITY MEASUREMENTS IN CAVITATING FLOWS USING FAST X-RAY IMAGING 
      Communication sans acte
      KHLIFA, Ilyass; FUZIER, Sylvie; HOCEVAR, Marko; VABRE, Alexandre; FEZZAA, Kamel; ccCOUTIER-DELGOSHA, Olivier (2013)
      A promising method to measure velocity fields in complex two-phase flows such us cavitating flows is presented. Dynamics of the liquid phase and the bubbles are both investigated. The measurements are based on ultra fast ...
    • Numerical simulation of flow field in water-pump sump and inlet suction pipe 
      Article dans une revue avec comité de lecture
      ccBAYEUL-LAINÉ, Annie-Claude; BOIS, Gérard; ISSA, Abir (IOP - Institute of Physics, 2010)
      There are several important considerations in the design of a suction supply sump. It is imperative that the amount of turbulence and entrained air be kept to a minimum. Free aircore vortex occurring at a water-intake pipe ...
    • 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 ...
    • Spectral analysis of unsteady flow simulation in a small VAWT 
      Communication avec acte
      BOIS, Gérard; ccSIMONET, Sophie; ccBAYEUL-LAINÉ, Annie-Claude (2012)
      The vertical axis wind turbine studied in this paper combine two rotations: one rotating movement of each blade around its own axis and one rotating movement around turbine’s axis. The aim of this paper is to analyse the ...
    • 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 ...
    • 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 ...
