    • A study of rotating stall in a vaneless diffuser of radial flow pump 
      Article dans une revue avec comité de lecture
      HENG, Yaguang; OUARZAZI, Mohamed Najib; SI, Qiaorui; ccDAZIN, Antoine (Taylor & Francis, 2018)
      Rotating stall in a vaneless diffuser of radial flow pump is studied. The measurements consist of: (i) unsteady pressure measurements delivered by two microphones; and (ii) nine steady pressure taps mounted in one radial ...
    • Investigations inside a vaned diffuser of a centrifugal pump at low flowrates. 
      Article dans une revue avec comité de lecture
      DUPONT, Patrick; BOIS, Gérard; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (IOP Publishing, 2016)
      This paper focuses on the unsteady flow behaviour inside the vaned diffuser of a radial flow pump model, operating at partial flowrates (0.387Qi, 0.584Qi and 0.766Qi where Qi is the impeller design flowrate).The effects ...
    • "Low Cost" Approaches for the Prediction of Rotating Instabilities in the Vaneless Diffuser of a Radial Flow Pump 
      Ouvrage scientifique
      ZHOU, Banglun; YUAN, Jianping; HENG, Yaguang; DUPONT, Patrick; OUARZAZI, Najib; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (Advances in Hydroinformatics, 2018)
      The instabilities, occurring in pumps operating at partial flow rates, may directly cause several negative effects, such as vibration, noise, mechanical damage. The present study is focused on the investigation of the ...
    • Canal lock variable speed hydropower turbine design and control 
      Article dans une revue avec comité de lecture
      ZHANGH, Jian; LEONTIDIS, Vlasios; TOUNZI, Abdelmounaim; DELARUE, Phillipe; CAIGNAERT, Guy; PIRIOU, Francis; LIBAUX, Antoine; ccDAZIN, Antoine (Wiley, 2018)
      The design of a novel submerged hydraulic turbine for producing electricity by converting the available hydropower on canal locks during raising and lowering ships, but with the minimum overall impact on the facility, is ...
    • Quantitative Design of a High Performance Permanent Magnet Vernier Generator 
      Article dans une revue avec comité de lecture
      ZHANG, Jian; TOUNZI, Abdelmounaim; DELARUE, Phillipe; PIRIOU, Francis; LEONTIDIS, Vlasios; CAIGNAERT, Guy; LIBAUX, Antoine; ccDAZIN, Antoine (Institute of Electrical and Electronics Engineers, 2017)
      Permanent-magnet vernier machines are becoming more and more attractive due to their high torque density and low-speed operating capabilities. This paper investigates the effects of the magnet thickness, magnet pole arc ...
    • Numerical Investigation of the Effects of Nonsinusoidal Motion Trajectory on the Propulsion Mechanisms of a Flapping Airfoil 
      Article dans une revue avec comité de lecture
      BOUDIS, A.; BENZAOUI, A.; OUALLI, H.; GUERRI, O.; ccCOUTIER-DELGOSHA, Olivier; ccBAYEUL-LAINÉ, Annie-Claude (American Society of Mechanical Engineers, 2019)
      The effect of nonsinusoidal trajectory on the propulsive performances and the vortex shedding process behind a flapping airfoil is investigated in this study. A movement of a rigid NACA0012 airfoil undergoing a combined ...
    • Development and validation of a one-dimensional transient rotodynamic pump model at component scale 
      Communication avec acte
      MATTEO, Laura; TAUVERON, Nicolas; ccDAZIN, Antoine (IOP Publishing, 2019)
      For reactor design and safety purposes, the French Alternative Energies and AtomicEnergy Commission (CEA) is currently working on the implementation of a predictive transienttwo-phase flow 4-quadrant rotodynamic pump ...
