    • External Laminar Boundary Layer Simulations Using a High-Fidelity Wall-Modeling Approach 
      Conférence invitée
      VIANA DAURICIO, Eron Tiago; ccJUNQUEIRA JUNIOR, Carlos; FEROLLA DE ABREU, Diego; AZEVEDO, João Luiz F. (ABCM, 2022-11)
      Wall-Modeled Large Eddy Simulation (WMLES) is a well-stablished technique for obtaining high-fidelity solutions of turbulent, high Reynolds number flows, with reasonably acceptable computational costs. However, for external ...
    • Self-similar temporal turbulent boundary layer flow 
      Article dans une revue avec comité de lecture
      ccBIAU, Damien (Elsevier BV, 2023-01)
      Direct numerical simulations of temporally evolving boundary layer flows are considered with solutions restricted to self-similar profiles. A new set of modified Navier–Stokes equations is solved with periodic boundary ...
    • Flow in a weakly curved square duct: Assessment and extension of Dean's model 
      Article dans une revue avec comité de lecture
      ccRIGO, Leonardo; ccBIAU, Damien; ccGLOERFELT, Xavier (American Physical Society (APS), 2021-02)
      The simplified model by W. R. Dean, based on a low-curvature assumption, provided an early understanding of the laminar flow in curved ducts. However, most of the following studies relied on computer simulations of the ...
    • Global stability, sensitivity and passive control of low-Reynolds-number flows around NACA 4412 swept wings 
      Article dans une revue avec comité de lecture
      ccNASTRO, Gabriele; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe; ccPASSAGGIA, Pierre-Yves; ccMAZELLIER, Nicolas (Cambridge University Press, 2023-01)
      The stability and sensitivity of two- and three-dimensional global modes developing on steady spanwise-homogeneous laminar separated flows around NACA 4412 swept wings are numerically investigated for different Reynolds ...
    • On the role of nonlinear correlations in reduced-order modelling 
      Article dans une revue avec comité de lecture
      CALLAHAM, Jared L.; BRUNTON, Steven L.; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2022-03)
      This work investigates nonlinear dimensionality reduction as a means of improving the accuracy and stability of reduced-order models of advection-dominated flows. Nonlinear correlations between temporal proper orthogonal ...
    • Nonlinear stochastic modelling with Langevin regression 
      Article dans une revue avec comité de lecture
      CALLAHAM, J. L.; RIGAS, G.; BRUNTON, S. L.; ccLOISEAU, Jean-Christophe (The Royal Society Publishing, 2021-06)
      Many physical systems characterized by nonlinear multiscale interactions can be modelled by treating unresolved degrees of freedom as random fluctuations. However, even when the microscopic governing equations and qualitative ...
    • Deep Recurrent Encoder: an end-to-end network to model magnetoencephalography at scale 
      Article dans une revue avec comité de lecture
      CHEHAB, Omar; DEFOSSEZ, Alexandre; GRAMFORT, Alexandre; KING, Jean-Remi; ccLOISEAU, Jean-Christophe (Neurons Behavior Data Analysis and Theory (NBDT), 2022-10)
      Understanding how the brain responds to sensory inputs from non-invasive brain recordings like magnetoencephalography (MEG) can be particularly challenging: (i) the high-dimensional dynamics of mass neuronal activity are ...
