    • Linear stability of optimal streaks in the log-layer of turbulent channel flows 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric (American Institute of Physics, 2015)
      The importance of secondary instability of streaks for the generation of vortical struc-tures attached to the wall in the logarithmic region of turbulent channels is studied. Thestreaks and their linear instability are ...
    • Permeability models affecting nonlinear stability in the asymptotic suction boundary layer: the Forchheimer versus the Darcy model 
      Article dans une revue avec comité de lecture
      WEDIN, Håkan; CHERUBINI, Stefania (IOP Publishing, 2016)
      The asymptotic suction boundary layer (ASBL) is used for studying two permeability models, namely the Darcy and the Forchheimer model, the latter being more physically correct according to the literature. The term that ...
    • Laminar supersonic sphere wake unstable bifurcations 
      Article dans une revue avec comité de lecture
      SANSICA, A.; OHMICHI, Y.; HASHIMOTO, A.; ccROBINET, Jean-Christophe (American Institute of Physics, 2020)
      The laminar sphere unstable bifurcations are sought at a Mach number of M∞ = 1.2. Global stability performed on steady axisymmetric base flows determines the regular bifurcation critical Reynolds number at Rereg cr = 650, ...
    • Simulation of Viscous Fingering Instability by the Lattice Boltzmann Method 
      Communication avec acte
      VIENNE, Lucien; MARIE, Simon; GRASSO, Francesco (American Institute of Aeronautics and Astronautics, 2019)
      The viscous fingering instability is successfully simulated within a lattice Boltzmann framework. Each species of the mixture is governed by its own kinetic equation and a force takes into account the diffusion between ...
    • Lattice Boltzmann method for miscible gases: A forcing-term approach 
      Article dans une revue avec comité de lecture
      VIENNE, Lucien; MARIÉ, Simon; GRASSO, Francesco (American Physical Society (APS), 2019)
      A lattice Boltzmann method for miscible gases is presented. In this model, the standard lattice Boltzmann method is employed for each species composing the mixture. Diffusion interaction among species is taken into account ...
    • An efficient mass-preserving interface-correction level set/ghost fluid method for droplet suspensions under depletion forces 
      Article dans une revue avec comité de lecture
      GE, Zhouyang; TAMMISOLA, Outi; BRANDT, Luca; ccLOISEAU, Jean-Christophe (Elsevier, 2018)
      Aiming for the simulation of colloidal droplets in microfluidic devices, we present here a numerical method for two-fluid systems subject to surface tension and depletion forces among the suspended droplets. The algorithm ...
    • Epoxy/amine reactive systems for composites materials and their thermomechanical properties 
      Chapitre d'ouvrage scientifique
      NONY, Fabien; FARZANEH, Sedigheh; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph; ccKHELLADI, Sofiane (Elsevier, 2015)
      In this chapter, epoxy/amines systems are studied during their synthesis and once they are synthesized. In the first part of this chapter, the different cross-linking mechanisms and their kinetics are presented. Then the ...
