    • "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 ...
    • Numerical study of a sinusoidal transverse propeller 
      Article dans une revue avec comité de lecture
      FASSE, Guillaume; CURUTCHET, A.; PAILLARD, B.; ccCOUTIER-DELGOSHA, Olivier; ccHAUVILLE, Frederic; ccBAYEUL-LAINÉ, Annie-Claude (IOP Publishing, 2019)
      In order to obtain higher propulsion efficiency for marine transportation, the authors have numerically tested a novel trochoidal propeller using a sinusoidal blade pitch function. The main results presented here are the ...
    • A Review of Design Considerations of Centrifugal Pump Capability for Handling Inlet Gas-Liquid Two-Phase Flows 
      Article dans une revue avec comité de lecture
      JIANG, Qifeng; HENG, Yaguang; LIU, Xiaobing; ZHANG, Weibin; BOIS, Gérard; SI, Qiaorui (MDPI, 2019)
      Most of the pumps working under two phase flows conditions are used in petroleum industry applications, like electrical submersible pumps (ESP) for hydrocarbon fluids, in chemistry, nuclear industries and in agriculture ...
    • Investigation on centrifugal pump performance degradation under air-water inlet two-phase flow conditions 
      Article dans une revue avec comité de lecture
      SI, Qiaorui; CUI, Qianglei; ZHANG, Keyu; YUAN, Jianping; BOIS, Gérard (EDP Sciences, 2018)
      In order to study the flow characteristics of centrifugal pumps when transporting the gas-liquid mixture, water and air were chosen as the working medium. Both numerical simulation and experimental tests were conducted on ...
    • 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 ...
    • Optimization of cavitating flows simulation with data driven approach: from data assimilation to machine learning 
      Communication avec acte
      ZHANG, Xinlei; GOMEZ, Thomas; XIAO, HENG; ccCOUTIER-DELGOSHA, Olivier (ASME Press, 2018)
      This paper investigates the application of data-driven approach to the optimization of cavitating flow simulations. An evaluation of the performance of commonly used RANS models (k-e, k-w and k-w SST) is presented by ...
    • 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
