    • Optimal bursts in turbulent channel flow 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (Springer Verlag, 2017)
      Bursts are recurrent, transient, highly energetic events characterized by localized variations of velocity and vorticity in turbulent wall-bounded flows. In this work, a nonlinear energy optimization strategy is employed ...
    • 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 ...
    • 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 ...
    • 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 ...
    • A time semi-implicit scheme for the energy-balanced coupling of a shocked fluid flow with a deformable structure 
      Article dans une revue avec comité de lecture
      PUSCAS, Maria Adela; MONASSE, Laurent; ERN, Alexandre; TENAUD, Christian; MARIOTTI, Christian; ccDARU, Virginie (Elsevier, 2015)
      The objective of this work is to present a conservative coupling method between an inviscid compressible fluid and a deformable structure undergoing large displacements. The coupling method combines a cut-cell Finite Volume ...
    • Multi-fidelity optimization strategy for the industrial aerodynamic design of helicopter rotor blades 
      Article dans une revue avec comité de lecture
      LEUSINK, Debbie; ALFANO, David; CINNELLA, Paola (Elsevier, 2015)
      The industrial aerodynamic design of helicopter rotor blades needs to consider the two typical flight conditions of hover and forward flight simultaneously. Here, this multi-objective design problem is tackled by using a ...
