    • Experimental Analysis of an Axial Compressor Operating under Flow Distorsion 
      Communication avec acte
      BARETTER, Alberto; ROUSSETTE, Olivier; ROMANO, Francesco; ccDAZIN, Antoine; ccJOSEPH, Pierric (ASME, 2022-06)
      In aircraft engines, compressor stages can encounter situations in which the flow is distorted at rotor inlet, for example during particular flight maneuvers, or due to the shape of the inlet of the airframe. The main ...
    • Experimental Flow Investigation Inside an Axial Compressor with Active Flow Control 
      Communication avec acte
      MOUBOGHA MOUBOGHA, Joseph; ROUSSETTE, Olivier; ccDAZIN, Antoine; ccJOSEPH, Pierric (ASME, 2022-06)
      This paper describes the experimental study of the flow behavior in a rotor blade channel of an axial compressor equipped with an Active Flow Control (AFC) system using Particle Image Velocimetry. The AFC system consists ...
    • Dynamics of high-speed drop impact on deep liquid pool 
      Communication avec acte
      WANG, Hui; LIU, Shuo; ccBAYEUL-LAINÉ, Annie-Claude; ccCOUTIER-DELGOSHA, Olivier (Department of Fluid Mechanics Budapest University of Technology and Economics, 2022-09)
      In this work, high-speed drop impact onto deep volume of the same liquid is numerically studied in 3D using Direct Numerical Simulation (DNS). The numerical results are compared with the previous experimental works by ...
    • Direct Numerical Simulation of Shallow Water Breaking Waves Generated by Wave Plate 
      Communication avec acte
      LIU, Shuo; WANG, Hui; ccCOUTIER-DELGOSHA, Olivier; ccBAYEUL-LAINÉ, Annie-Claude (Department of Fluid Mechanics Budapest University of Technology and Economics, 2022-09)
      We present direct numerical simulation of breaking waves in shallow water generated by the wave plate. The open-source Basilisk solver is used to solve the incompressible, variable-density, twophase Navier-Stokes equations ...
    • Stall Margin Improvement in an Axial Compressor by Continuous and Pulsed Tip Injection 
      Article dans une revue avec comité de lecture
      MOUBOGHA MOUBOGHA, Joseph; MARGALIDA, Gabriel; ROUSSETTE, Olivier; ccDAZIN, Antoine; ccJOSEPH, Pierric (MDPI AG, 2022-03)
      Stall and surge are strong limitations in the operating range of compressors and thus one of the major limits of jet engine performance. A promising way to push the stability limit of compression machines is to inject a ...
    • Analysis of flow-induced performance change of cycloidal rotors: Influence of pitching kinematic and chord-to-radius ratio 
      Article dans une revue avec comité de lecture
      SHI, Lei; ccCOUTIER-DELGOSHA, Olivier; ccBAYEUL-LAINÉ, Annie-Claude (Elsevier ltd, 2022-08)
      As a new type of the propulsive devices, cycloidal rotor has been attracting more attention recently. The present work concentrates on the analysis of the performance and internal flow field of a two-bladed cycloidal ...
    • Numerical investigations on unsteady vortical flows and separation-induced transition over a cycloidal rotor at low Reynolds number 
      Article dans une revue avec comité de lecture
      SHI, Lei; ccCOUTIER-DELGOSHA, Olivier; ccBAYEUL-LAINÉ, Annie-Claude (Elsevier BV, 2022-08)
      The unsteady vortical flows and laminar-turbulence transition over a 2-bladed cycloidal rotor are investigated numerically at two advance coefficients, with special emphasis on the influence of two turbulence models, ...
