    • Investigation of the dynamics in separated turbulent flow 
      Article dans une revue avec comité de lecture
      FADLA, Fawzi; ALIZARD, Frédéric; KEIRSBULCK, Laurent; LAVAL, Jean-Philippe; FOUCAUT, Jean-Marc; CHOVET, Camila; LIPPERT, Marc; ccROBINET, Jean-Christophe (Elsevier, 2019)
      Dynamical behavior of the turbulent channel flow separation induced by a wall-mounted two-dimensional bump is studied, with an emphasis on unsteadiness characteristics of vortical motions evolving in the separated flow. ...
    • Various approaches to determine active regions in an unstable global mode: application to transonic buffet 
      Article dans une revue avec comité de lecture
      PALADINI, Edoardo; MARQUET, Olivier; SIPP, Denis; DANDOIS, Julien; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2019)
      The transonic flow field around a supercritical airfoil is investigated. The objective of the present paper is to enhance the understanding of the physical mechanics behind two-dimensional transonic buffet. The paper is ...
    • A synthetic forcing to trigger laminar-turbulent transition in parallel wall bounded flows via receptivity 
      Article dans une revue avec comité de lecture
      PICELLA, Francesco; BUCCI, Michele Alessandro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (Elsevier, 2019)
      Research on laminar-turbulent transition of wall-bounded parallel flows has usually focused on controlled scenarios where transition is triggered by perturbations having simple shapes and spectra. These disturbances strongly ...
    • Analysis and Comparison of Transonic Buffet Phenomenon over Several Three-Dimensional Wings 
      Article dans une revue avec comité de lecture
      PALADINI, Edoardo; DANDOIS, Julien; SIPP, Denis; ccROBINET, Jean-Christophe (American Institute of Aeronautics and Astronautics, 2019)
      The transonic buffet is a complex aerodynamic instability that appears on wings and airfoils at a high subsonic Mach number and/or angle of attack. It consists of a shock oscillation that induces pressure and notably lift ...
    • Transonic buffet instability: From two-dimensional airfoils to three-dimensional swept wings 
      Article dans une revue avec comité de lecture
      PALADINI, Edoardo; BENEDDINE, Samir; DANDOIS, Julien; SIPP, Denis; ccROBINET, Jean-Christophe (American Physical Society, 2019)
      The objective of the present study is to explain the evolution of the transonic buffet phenomenon from two-dimensional airfoils to three-dimensional swept wings by a global stability analysis. With respect to two-dimensional ...
    • 3D global hydrodynamic stability analysis of a diffusion flame 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; MANCINI, C.; DE PALMA, Pietro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (IOP Publishing, 2018)
      This work investigates the three-dimensional global hydrodynamic stability of a diffusion flame. The low-Mach-number (LMN) Navier-Stokes (NS) equations for reacting flows are solved together with a transport equation for ...
    • Computing heteroclinic orbits using adjoint-based methods 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; SCHNEIDER, T. M.; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2018)
      Transitional turbulence in shear flows is supported by a network of unstable exact invariant solutions of the Navier–Stokes equations. The network is interconnected by heteroclinic connections along which the turbulent ...
