    • Instabilities in oblique shock wave/laminar boundary-layer interactions 
      Article dans une revue avec comité de lecture
      GUIHO, F.; ALIZARD, Frédéric; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2016)
      The interaction of an oblique shock wave and a laminar boundary layer developing over a flat plate is investigated by means of numerical simulation and global linear-stability analysis. Under the selected flow conditions ...
    • 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 ...
    • Global stability analysis of lifted diffusion flames 
      Article dans une revue avec comité de lecture
      MANCINI, C.; FARANO, Mirko; DE PALMA, Pietro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (Elsevier, 2017)
      This work describes the development of a method for the global hydrodynamic stability analysis of diffusion flames. The low-Machnumber (LMN) Navier–Stokes (NS) equations for reacting flows are solved together with a transport ...
    • 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 ...
    • 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. ...
    • 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 ...
    • Subcritical transition scenarios via linear and nonlinear localized optimal perturbations in plane Poiseuille flow 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (IOP Publishing, 2016)
      Subcritical transition in plane Poiseuilleflow is investigated by means of aLagrange-multiplier direct-adjoint optimization procedure with the aim offinding localized three-dimensional perturbations optimally growing in a ...
