    • Nonlinear optimals in the asymptotic suction boundary layer: Transition thresholds and symmetry breaking 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (American Institute of Physics, 2015)
      The effect of a constant homogeneous wall suction on the nonlinear transient growth of localized finite amplitude perturbations in a boundary-layer flow is investigated. Using a variational technique, nonlinear optimal ...
    • 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 ...
    • Effect of plate permeability on nonlinear stability of the asymptotic suction boundary layer 
      Article dans une revue avec comité de lecture
      WEDIN, Hakan; CHERUBINI, Stefania; BOTTARO, Alessandro (American Physical Society, 2015)
      The nonlinear stability of the asymptotic suction boundary layer is studied numerically, searching for finite-amplitude solutions that bifurcate from the laminar flow state. By changing the boundary conditions for disturbances ...
    • POD study of aerated cavitation in a venturi nozzle 
      Communication avec acte
      TOMOV, Petar; DANLOS, Amélie; ccRAVELET, Florent; ccSARRAF, Christophe; ccBAKIR, Farid; ccKHELLADI, Sofiane (IOP sciences conference series, 2015)
      The fact of injecting bubbles into a cavitating flow influences typical cavitating behavior. Cavitation and aerated cavitation experiments has been carried out on a symmetrical venturi nozzle with convergent/divergent ...
    • 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 ...
    • The first-digit frequencies in data of turbulent flows 
      Article dans une revue avec comité de lecture
      ccBIAU, Damien (Elsevier, 2015)
      Considering the first significant digits (noted image) in data sets of dissipation for turbulent flows, the probability to find a given number (image or 2 or …9) would be 1/9 for a uniform distribution. Instead the probability ...
    • Review and Perspectives: Shape Memory Alloy Composite Systems 
      Article dans une revue avec comité de lecture
      LESTER, Brian; BAXEVANIS, Theocaris; CHEMISKY, Yves; LAGOUDAS, Dimitris (Springer Verlag, 2015)
      Following their discovery in the early 60's, there has been a continuous quest for ways to take advantage of the extraordinary properties of shape memory alloys (SMAs). These intermetallic alloys can be extremely compliant ...
