    • Adaptive filtering for the lattice Boltzmann method 
      Article dans une revue avec comité de lecture
      MARIÉ, Simon; ccGLOERFELT, Xavier (Elsevier, 2017)
      In this study, a new selective filtering technique is proposed for the Lattice Boltzmann Method. This technique is based on an adaptive implementation of the selective filter coefficient σ. The proposed model makes the ...
    • Experimental investigation of an actively controlled automotive cooling fan using steady air injection in the leakage gap 
      Article dans une revue avec comité de lecture
      AZZAM, Tarik; PARIDAENS, Richard; OUALLI, Hamid; ccRAVELET, Florent; ccBAKIR, Farid; ccKHELLADI, Sofiane (SAGE Publications, 2017)
      In an axial fan, a leakage flow driven by a pressure gradient between the pressure side and the suction side occurs in the gap between the shroud and the casing. This leakage flow is in the opposite direction to the main ...
    • A framework for closed-loop flow control using the parabolized stability equations 
      Communication avec acte
      SASAKI, Kenzo; CAVALIERI, André V. G.; SILVESTRE, Flávio J.; JORDAN, Peter; TISSOT, Gilles; ccBIAU, Damien (American Institute of Aeronautics and Astronautics, 2017)
      We develop a reduced-order-model framework using the parabolized stability equations and identification techniques for the closed-loop control of unsteady fluctuations along fluidic systems. These models had been successfully ...
    • Aeroacoustic Study of the Interaction of a Rotating Blade with a Batchelor Vortex 
      Article dans une revue avec comité de lecture
      ZEHNER, Paul; FALISSARD, Fabrice; ccGLOERFELT, Xavier (American Institute of Aeronautics and Astronautics, 2018)
      The aeroacoustic response of the orthogonal interaction of a rotating blade with an isolated Batchelor vortex is studied by means of numerical simulation. The relative influence of the vortex tangential and axial velocity ...
    • Optimal perturbation for two-dimensional vortex systems: route to non-axisymmetric state 
      Article dans une revue avec comité de lecture
      NAVROSE; JOHNSON, Author H. G.; BRION, Véronique; JACQUIN, Laurent; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2018)
      We investigate perturbations that maximize the gain of disturbance energy in a two-dimensional isolated vortex and a counter-rotating vortex pair. The optimization is carried out using the method of Lagrange multipliers. ...
    • A high-order density-based finite volume method for the computation of all-speed flows 
      Article dans une revue avec comité de lecture
      NOGUEIRA, Xesús; RAMÍREZ, Luis; CHASSAING, Jean-Camille; COLOMINAS, Ignasi; ccKHELLADI, Sofiane (Elsevier, 2016)
      In this paper we present a high-order density-based finite-volume framework for all-speed flows. The formulation is based on high-order variable reconstructions performed using Moving Least Squares approximations. In ...
    • In Vivo Assessment of Elasticity of Child Rib Cortical Bone Using Quantitative Computed Tomography 
      Article dans une revue avec comité de lecture
      ZHU, Y.; BERMOND, François; PAYEN DE LA GARANDERIE, J.; PIALAT, J.-B.; ccSANDOZ, Baptiste; BRIZARD, D.; PRACROS, J.-P.; RONGIERAS, F.; ccSKALLI, Wafa; MITTON, David (Hindawi, 2017)
      Elasticity of the child rib cortical bone is poorly known due to the difficulties in obtaining specimens to perform conventional tests. It was shown on the femoral cortical bone that elasticity is strongly correlated with ...
