    • 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 ...
    • 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 ...
    • 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 ...
    • Hairpin-like optimal perturbations in plane Poiseuille flow 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2015)
      In this work it is shown that hairpin vortex structures can be the outcome of a nonlinear optimal growth process, in a similar way as streaky structures can be the result of a linear optimal growth mechanism. With this ...
    • 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 ...
    • Minimal-energy perturbations rapidly approaching the edge state in Couette flow 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; DE PALMA, Pietro (Cambridge University Press (CUP), 2015)
      Transition to turbulence in shear flows is often subcritical, thus the dynamics of the flow strongly depends on the shape and amplitude of the perturbation of the laminar state. In the state space, initial perturbations ...
    • 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 ...
