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.

  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, ...

  Nonlinear optimal perturbation of turbulent channel flow as a precursor of extreme events 

  Article dans une revue avec comité de lecture

  CIOLA, Nicola; DE PALMA, Paul; ROBINET, Jean-Christophe; CHERUBINI, Stefania (Cambridge University Press (CUP), 2023-08)

  This work aims at studying the mechanisms behind the occurrence of extreme dissipation events in a channel flow, identifying nonlinear optimal perturbations as potential precursors of these events. Nonlinear optimal ...

  Numerical Analysis of Distance Effect between Inducer and Centrifugal Impeller in Independent Rotational Turbopump in Co-rotating and Counter-rotating Mode 

  Communication avec acte

  DEHNAVI, Ehsan; BAKIR, Farid; DANLOS, Amélie; KEBDANI, Mohamed (Euroturbo (European Turbomachinery Society), 2023-04)

  This study focuses on enhancing the performance of turbomachines through the design of multi rotor configurations. Specifically, the effect of the distance between an axial inducer and a centrifugal impeller, which rotates ...

  Instability mechanisms in meandering streamwise vortex pairs of upswept afterbody wakes 

  Article dans une revue avec comité de lecture

  RANJAN, Rajesh; ROBINET, Jean-Christophe; GAITONDE, Datta (Elsevier BV, 2022-07)

  Wakes of upswept afterbodies are often characterized by counter-rotating streamwise vortex pairs which meander in space. One application concerns aft regions of cargo aircraft, which are characterized by a relatively flat ...

  Minimal energy thresholds for sustained turbulent bands in channel flow 

  Article dans une revue avec comité de lecture

  PARENTE, Enza; ROBINET, Jean-Christophe; DE PALMA, Paul; CHERUBINI, Stefania (Cambridge University Press (CUP), 2022-05)

  In this work, nonlinear variational optimization is used for obtaining minimal seeds for the formation of turbulent bands in channel flow. Using nonlinear optimization together with energy bisection, we have found that the ...
