      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 ...

      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 ...

      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 ...

      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 ...

      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 ...

      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 ...

      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 ...
