    • 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 ...
    • 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 ...
    • Numerical Study of Multistage Transcritical Organic Rankine Cycle Axial Turbines 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; ccSCIACOVELLI, Luca (American Society of Mechanical Engineers, 2014)
      Transonic flows through axial, multi-stage, transcritical ORC turbines, are investigated by using a numerical solver including advanced multiparameter equations of state and a high-order discretization scheme. The working ...
    • Bayesian quantification of thermodynamic uncertainties in dense gas flows 
      Article dans une revue avec comité de lecture
      MERLE, Xavier; CINNELLA, Paola (Elsevier, 2015)
      A Bayesian inference methodology is developed for calibrating complex equations of state used in numerical fluid flow solvers. Precisely, the input parameters of three equations of state commonly used for modeling the ...
    • 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 ...
    • Convergence of Fourier-based time methods for turbomachinery wake passing problems 
      Article dans une revue avec comité de lecture
      GOMAR, Adrien; BOUVY, Quentin; SICOT, Frédéric; DUFOUR, Guillaume; CINNELLA, Paola; FRANCOIS, Benjamin (Elsevier, 2014)
      The convergence of Fourier-based time methods applied to turbomachinery flows is assessed. The focus is on the harmonic balance method, which is a timedomain Fourier-based approach standing as an efficient alternative to ...
