Le Laboratoire DynFluid (équipe d'accueil EA 92) est un laboratoire en cotutelle Arts et Métiers ParisTech / Conservatoire National des Arts et Métiers. Il mène des travaux de recherche en Mécanique des fluides, Aérodynamique et Acoustique, avec des applications dans les secteurs aéronautique, automobile et celui des procédés industriels. Il développe des méthodes numériques originales pour simuler des écoulements (le plus souvent en régime compressible) et des phénomènes aéroacoustiques, ou analyser leurs instabilités et il met en œuvre ces méthodes dans le cadre de programmes de recherche nationaux ou internationaux. Le laboratoire collabore également avec de nombreux partenaires industriels et académiques.

  Linear stability of Rayleigh-Bénard-Poiseuille flow of water near 4°C in a channel bounded by slip walls 

  Article dans une revue avec comité de lecture

  BENBEGHILA, Aymen; OUZANI, Riadh; BENDERRADJI, Ammar; ALLOUI, Zineddine; KHELLADI, Sofiane (Elsevier BV, 2024-11)

  The onset of mixed convection of cold water in a horizontal channel is studied using linear stability analysis. The two walls of the channel are modeled using slip conditions and are maintained at different constant ...

  Turbulent transition in a channel with superhydrophobic walls: anisotropic slip and shear misalignment effects 

  Article dans une revue avec comité de lecture

  JOUIN, Antoine; CHERUBINI, Stefania; ROBINET, Jean-Christophe (Cambridge University Press (CUP), 2024-02)

  Superhydrophobic surfaces dramatically reduce skin friction of overlying liquid flows. These surfaces are complex and numerical simulations usually rely on models to reduce this complexity. One of the simplest consists of ...

  Modal and nonmodal stability analysis of turbulent stratified channel flows 

  Article dans une revue avec comité de lecture

  VARIALE, Donato; PARENTE, Enza; ROBINET, Jean-Christophe; CHERUBINI, Stefania (Purpose-Led Publishing (AIP Publishing, American Physical Society - APS - and IOP Publishing), 2024-01)

  Unstable or optimally growing perturbations of turbulent flows are often representative of the energy-containing coherent structures populating the flow, as for streaks in a turbulent channel. Within this framework, this ...

  Impinging shear layer instability in over-expanded nozzle dynamics 

  Article dans une revue avec comité de lecture

  TARSIA MORISCO, Cosimo; ROBINET, Jean-Christophe; HERPE, Julien; SAUCEREAU, Didier (AIP Publishing, 2023-11)

  When rocket engine nozzles operate at a high degree of over-expansion, an internal flow separation occurs with a strong unsteady shock–wave boundary layer interaction. The global dynamics results in a low-frequency mode, ...
