    • On compressibility assumptions in aeroacoustic integrals: a numerical study with subsonic mixing layers 
      Article dans une revue avec comité de lecture
      MARGNAT, Florent; ccGLOERFELT, Xavier (Acoustical Society of America, 2014)
      Two assumptions commonly made in predictions based on Lighthill’s formalism are investigated: a constant density in the quadrupole expression, and the evaluation of the source quantity from incompressible simulations. ...
    • Impact of Thermal Aging on the Microstructure Evolution and Mechanical Properties of Lanthanum-Doped Tin-Silver-Copper Lead-Free Solders 
      Article dans une revue avec comité de lecture
      SADIQ, Muhammad; CHERKAOUI, Mohammed; ccPESCI, Raphaël (Institute of Electrical and Electronics Engineers, 2013)
      An extensive study is made to analyze the impact of pure lanthanum on the microstructure and mechanical properties of Sn-Ag-Cu (SAC) alloys at high temperatures. Different compositions are tested; the temperature applied ...
    • Minimal perturbations approaching the edge of chaos in a Couette flow 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; DE PALMA, Pietro (IOP Publishing, 2014)
      This paper provides an investigation of the structure of the stable manifold of the lower branch steady state for the plane Couette flow. Minimal energy perturbations to the laminar state are computed, which approach within ...
    • Investigation of wind turbine flow and wake 
      Article dans une revue avec comité de lecture
      MASSOUH, Fawaz; DOBREV, Ivan (2014)
      This paper is dedicated to the investigation and analysis of wind turbine wake. An experimental work is undertaken in wind tunnel on a horizontal axis wind turbine model. The velocity field in the wake is measured using ...
    • A domain decomposition matrix-free method for global linear stability 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (Elsevier, 2012)
      This work is dedicated to the presentation of a matrix-free method for global linear stability analysis in geometries composed of multi-connected rectangular subdomains. An Arnoldi technique using snapshots in subdomains ...
    • Global and Koopman modes analysis of sound generation in mixing layers 
      Article dans une revue avec comité de lecture
      SONG, Ge; ALIZARD, Frédéric; ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (American Institute of Physics, 2013)
      It is now well established that linear and nonlinear instability waves play a significant role in the noise generation process for a wide variety of shear flows such as jets or mixing layers. In that context, the problem ...
    • Turbulent boundary layer noise : direct radiation at Mach number 0.5 
      Article dans une revue avec comité de lecture
      BERLAND, Julien; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2013)
      Boundary layers constitute a fundamental source of aerodynamic noise. A turbulent boundary layer over a plane wall can provide an indirect contribution to the noise by exciting the structure, and a direct noise contribution. ...
