    • Effect of time-varying freestream on performance and vortex dynamics of forward and reversed pitching airfoils 
      Article dans une revue avec comité de lecture
      SHI, Lei; WANG, Yefang; ccBAYEUL-LAINÉ, Annie-Claude; ccCOUTIER-DELGOSHA, Olivier (Elsevier BV, 2022)
      The goal of the present work deals with the influence of the oscillating freestream on the global performance, transition and vortex dynamics of forward and reversed airfoils. Three important parameters, involving the ...
    • 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 ...
    • 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 ...
    • Numerical study of a sinusoidal transverse propeller 
      Communication avec acte
      FASSE, Guillaume; ccBAYEUL-LAINÉ, Annie-Claude; ccCOUTIER-DELGOSHA, Olivier; CURUTCHET, Arnaud; PAILLARD, Benoît; ccHAUVILLE, Frederic (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 ...
    • 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 ...
    • Investigation on the influence of jetting equipment on the characteristics of centrifugal pump 
      Article dans une revue avec comité de lecture
      SI, Qiaorui; YUAN, Shouqi; YUAN, Jianping; BOIS, Gérard (Sage Journals, 2016)
      To reduce radial noises from the motor of centrifugal pumps, this study designed a water cooling system called jettingequipment to replace traditional fan cooling systems in pump motors. By measuring radiated noises, head, ...
    • 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. ...
