    • Bioinspired turbine blades offer new perspectives for wind energy 
      Article dans une revue avec comité de lecture
      COGNET, Vincent; COURRECH DU PONT, Sylvain; DOBREV, Ivan; MASSOUH, Fawaz; THIRIA, Benjamin (Royal Society, The, 2017)
      Wind energy is becoming a significant alternative solution for future energy production. Modern turbines now benefit from engineering expertise, and a large variety of different models exists, depending on the context and ...
    • Approach for numerical modeling of airfoil dynamic stall 
      Communication avec acte
      VELKOVA, Cvetelina; DOBREV, Ivan; TODOROV, Michael; MASSOUH, Fawaz (BulTrans-2012, 2012)
      The aim of the computational study is to present different approach for numerical modeling of airfoil dynamic stall as the airfoil is pitched at a constant rate from zero incidences to a high angle of attack. An application ...
    • Transient growth of perturbations in Stokes oscillatory flows 
      Article dans une revue avec comité de lecture
      ccBIAU, Damien (Cambridge University Press (CUP), 2016)
      Oscillatory Stokes flows, with zero mean, are subjected to subcritical transition to turbulence. The maximal energy growth of perturbations is computed in the subcritical regime through an optimisation method. The results ...
    • Experimental study of blade thickness effects on the overall and local performances of a Controlled Vortex Designed axial-flow fan 
      Article dans une revue avec comité de lecture
      SARRAF, Christophe; NOURI, Hussain; RAVELET, Florent; BAKIR, Farid (Elsevier, 2011)
      The purpose of this work is to study the effects of blade thickness on the performances of an axial-flow fan. Two fans that differ only in the thickness of their blades were studied. The first fan was designed to be part of ...
    • Study of passive control study of the cavitation instability on a venturi profile 
      Communication avec acte
      DANLOS, Amélie; MEHAL, Jean-Elie; ccRAVELET, Florent; ccSARRAF, Christophe (2010)
      This paper presents experimental and numerical results concerning the operation of a configuration that includes an axial pump and a bundle of tubes that mimics the cool source of a heat exchanger. The pump used in the ...
    • Early evolution of the compressible mixing layer issued from two turbulent streams 
      Article dans une revue avec comité de lecture
      PIROZZOLI, Sergio; BERNARDINI, Matteo; MARIÉ, Simon; GRASSO, Francesco (Cambridge University Press (CUP), 2015)
      Direct numerical simulation of the spatially developing mixing layer issuing from two turbulent streams past a splitter plate is carried out under mild compressibility conditions. The study mainly focuses on the early ...
    • Dynamical selective ltering for the Lattice Boltzmann Method 
      Communication avec acte
      MARIÉ, Simon; ccGLOERFELT, Xavier (AIAA, 2015)
      In this study, a new selective ltering technique is proposed for the Lattice Boltzmann Method. This technique is based on dynamical implementation of the selective filter coefficient . The proposed model makes the latter ...
