    • Toward improved simulation tools for compressible turbomachinery: assessment of Residual-Based Compact schemes for the transonic compressor NASA Rotor 37 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; MICHEL, Bruno (Taylor & Francis, 2014)
      Residual-based-compact schemes (RBC) of 2nd and 3rd-order accuracy are applied to a challenging 3D ow through a transonic compressor. The proposed schemes provide almost mesh-converged solutions in good agreement with ...
    • Predictive RANS simulations via Bayesian Model-Scenario Averaging 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola (Elsevier, 2014)
      The turbulence closure model is the dominant source of error in most Reynolds-Averaged Navier–Stokes simulations, yet no reliable estimators for this error component currently exist. Here we develop a stochastic, a posteriori ...
    • Banc de test pour stent 
      Brevet
      MAUREL, Blandine; LERMUSIAUX, Patrick; ccSARRAF, Christophe; ccBAKIR, Farid (2013)
      L'invention concerne un banc test pour stents, caractérisé en ce qu'il comprend une pompe (2) non volumétrique dont l'entrée est raccordée à un réservoir (4) de liquide sanguin ouvert et dont la sortie est reliée à une ...
    • Critical evaluation of three hemodynamic models for the numerical simulation of intra-stent flows 
      Article dans une revue avec comité de lecture
      CHABI, Fatiha; ccCHAMPMARTIN, Stephane; ccSARRAF, Christophe; NOGUERA, Ricardo (Elsevier, 2015)
      We evaluate here three hemodynamic models used for the numerical simulation of bare and stented artery flows. We focus on two flow features responsible for intra-stent restenosis: the wall shear stress and the re-circulation ...
    • Idle Operation with Low Intake Valve Lift in a Port Fuel Injected Engine 
      Article dans une revue avec comité de lecture
      CLENCI, Adrian; BIZIAC, Adrian; PODEVIN, Pierre; DESCOMBES, Georges; NICULESCU, Rodica; ccDELIGANT, Michael (MDPI, 2013)
      Reducing fuel consumption is a prime objective in the automotive industry in order to meet regulatory and customer demands. Variable valve actuation offers many opportunities for improving the spark ignition engine’s ...
    • Influence of Reynolds number and forcing type in a turbulent von Karman flow 
      Article dans une revue avec comité de lecture
      SAINT-MICHEL, Brice; DUBRULLE, Bérengère; MARIÉ, Louis; DAVIAUD, François; ccRAVELET, Florent (Institute of Physics: Open Access Journals, 2014)
      We present a detailed study of a global bifurcation occuring in a turbulent von Kármán swirling flow. In this system, the statistically steady states progressively display hysteretic behaviour when the Reynolds number is ...
    • Determination of wind turbine far wake using actuator disk 
      Communication avec acte
      AMER, Rodeyna; DOBREV, Ivan; MASSOUH, Fawaz (2014)
      The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of ...
