    • Analysis of the Unsteady Flow Around a Hydrofoil at Various Incidences 
      Chapitre d'ouvrage scientifique
      SHI, Lei; ccCOUTIER-DELGOSHA, Olivier; ccBAYEUL-LAINÉ, Annie-Claude (Springer, 2020)
      The oscillating hydrofoils used in underwater propulsion devices often experience large variations of the flow incidence, which favors cavitation at large angle of attack, and therefore a severe degradation of the performance, ...
    • Active flow control in an axial compressor for stability improvement : On the effect of flow control on stall inception 
      Article dans une revue avec comité de lecture
      MARGALIDA, Gabriel; ROUSSETTE, Olivier; ccDAZIN, Antoine; ccJOSEPH, Pierric (Springer Verlag (Germany), 2021)
      In this paper, the effect of an active flow control system on the onset mechanism of rotating stall in an axial compressor is experimentally investigated. A particular emphasis is thus given on the flow patterns present ...
    • Effects of Non-Sinusoidal Motion and Effective Angle of Attack on Energy Extraction Performance of a Fully- Activated Flapping Foil 
      Article dans une revue avec comité de lecture
      BOUDIS, A.; OUALLI, H.; BENZAOUI, A.; GUERRI, O; ccBAYEUL-LAINÉ, Annie-Claude; ccCOUTIER-DELGOSHA, Olivier (Journal of Applied Fluid Mechanics, 2021)
      Flapping foil energy harvesting systems are considered as highly competitive devices for conventional turbines. Several research projects have already been carried out to improve performances of such new devices. This paper ...
    • Numerical study of a sinusoidal transverse propeller 
      Communication avec acte
      FASSE, Guillaume; CURUTCHET, Arnaud; PAILLARD, Benoît; ccCOUTIER-DELGOSHA, Olivier; ccHAUVILLE, Frederic; ccBAYEUL-LAINÉ, Annie-Claude (2018)
      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 ...
    • Experimental Investigations on the Inner Flow Behavior of Centrifugal Pumps under Inlet Air-Water Two-Phase Conditions 
      Article dans une revue avec comité de lecture
      SI, Qiaorui; ZHANG, Haoyang; BOIS, Gérard; ZHANG, Jinfeng; CUI, Qianglei; YUAN, Shouqi (MDPI, 2019)
      Centrifugal pumps are widely used and are known to be sensitive to inlet air-water two-phase flow conditions. The pump performance degradation mainly depends on the changes in the two-phase flow behavior inside the pump. ...
    • CHEMO-MECHANICAL MODEL FOR PREDICTING THE LIFETIME OF EPDM RUBBERS 
      Article dans une revue avec comité de lecture
      HASSINE, Mouna Ben; NAIT-ABELAZIZ, Moussa; ccCOLIN, Xavier (American Chemical Society, 2019)
      A chemo-mechanical model has been developed for predicting the long-term mechanical behavior of EPDM rubbers in a harsh thermal oxidative environment. Schematically, this model is composed of two complementary levels: The ...
    • Effects of Surface Tension and Yield Stress on Mucus Plug Rupture: a Numerical Study 
      Article dans une revue avec comité de lecture
      HU, Yingying; ROMANO, Francesco; GROTBERG, James B. (American Society of Mechanical Engineers, 2019)
      We study the effects of surface tension and yield stress on mucus plug rupture. A three-dimensional simplified configuration is employed to simulate mucus plug rupture in a collapsed lung airway of the 10 th generation. ...
