    • On the scalability of CFD tool for supersonic jet flow configurations 
      Article dans une revue avec comité de lecture
      JUNQUEIRA-JUNIOR, Carlos; AZEVEDO, João Luiz F.; PANETTA, Jairo; WOLF, William R.; YAMOUNI, Sami (Elsevier, 2020)
      New regulations are imposing noise emissions limitations for the aviation industry which are pushing researchers and engineers to invest efforts in studying the aeroacoustics phenomena. Following this trend, an in-house ...
    • PySINDy: A Python package for the sparse identification of nonlinear dynamical systems from data 
      Article dans une revue avec comité de lecture
      DE SILVA, Brian; CHAMPION, Kathleen; QUADE, Markus; KUTZ, J. Nathan; BRUNTON, Steven; ccLOISEAU, Jean-Christophe (Open Journals, 2020)
      Scientists have long quantified empirical observations by developing mathematical models that characterize the observations, have some measure of interpretability, and are capable of making predictions. Dynamical systems ...
    • On the linear receptivity of trailing vortices 
      Article dans une revue avec comité de lecture
      BÖLLE, Tobias; BRION, Vincent; SIPP, Denis; JACQUIN, Laurent; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2020)
      The present work investigates the excitation process by which free-stream disturbances are transformed into vortex-core perturbations. This problem of receptivity is modelled in terms of the resolvent in frequency space ...
    • An efficient high-order compact scheme for the unsteady compressible Euler and Navier–Stokes equations 
      Article dans une revue avec comité de lecture
      LERAT, Alain (Elsevier, 2016)
      Residual-Based Compact (RBC) schemes approximate the 3-D compressible Euler equations with a 5th- or 7th-order accuracy on a 5 × 5 × 5-point stencil and capture shocks pretty well without correction. For unsteady flows ...
    • The influence of a pressure wavepacket's characteristics on its acoustic radiation 
      Article dans une revue avec comité de lecture
      SERRÉ, R.; MARGNAT, F.; ccROBINET, Jean-Christophe (Acoustical Society of America, 2015)
      Noise generation by flows is modeled using a pressure wavepacket to excite the acoustic medium via a boundary condition of the homogeneous wave equation. The pressure wavepacket is a generic representation of the flow ...
    • Global Instability in Shock Wave Laminar Boundary-Layer Interaction 
      Communication avec acte
      GUIHO, F.; ALIZARD, Frédéric; ccROBINET, Jean-Christophe (Springer, 2015)
      The linear global stability of an interaction between an oblique shock wave and a laminar boundary layer is carried out for various oblique shock angles. It is illustrated that such a flow acts as a noise amplifier. The ...
    • Weakly nonlinear optimal perturbations 
      Article dans une revue avec comité de lecture
      PRALITS, Jan O.; BOTTARO, Alessandro; CHERUBINI, Stefania (Cambridge University Press (CUP), 2015)
      A simple approach is described for computing spatially extended, weakly nonlinear optimal disturbances, suitable for maintaining a disturbance-regeneration cycle in a simple shear flow. Weakly nonlinear optimals, computed ...
