    • Smoothed Particle Hydrodynamics: A consistent model for interfacial multiphase fluid flow simulations 
      Article dans une revue avec comité de lecture
      KRIMI, Abdelkader; REZOUG, Mehdi; NOGUEIRA, Xesús; RAMÍREZ, Luis; ccDELIGANT, Michael; ccKHELLADI, Sofiane (Elsevier, 2018)
      In this work, a consistent Smoothed Particle Hydrodynamics (SPH) model to deal with interfacial multiphase fluid flows simulation is proposed. A modification to the Continuum Stress Surface formulation (CSS) [1] to enhance ...
    • Modal and non-modal linear stability of Poiseuille flow through a channel with a porous substrate 
      Article dans une revue avec comité de lecture
      GHOSH, Souvik; BREUGEM, Wim-Paul; BRANDT, Luca; ccLOISEAU, Jean-Christophe (Elsevier, 2019)
      We present modal and non-modal linear stability analyses of Poiseuille flow through a plane channel with a porous substrate modeled using the Volume Averaged Navier–Stokes (VANS) equations. Modal stability analysis shows ...
    • Study of Bonding Formation between the Filaments of PLA in FFF Process 
      Article dans une revue avec comité de lecture
      KALLEL, Achraf; ccKOUTIRI, Imade; BABAEITORKAMANI, E.; KHAVANDI, A.; TAMIZIFAR, M.; ccSHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas (2019)
      Fused filament fabrication (FFF) is an additive manufacturing (AM) process that provides physical objects commonly used for modeling, prototyping and production applications. The major drawback of this process is poor ...
    • 1/f noise and long-term memory of coherent structures in a turbulent shear flow 
      Article dans une revue avec comité de lecture
      GISSINGER, C.; FAUVE, S.; ccPEREIRA, Michaël (American Physical Society (APS), 2019)
      A shear flow of liquid metal (Galinstan) is driven in an annular channel by counter-rotating traveling magnetic fields imposed at the endcaps. When the traveling velocities are large, the flow is turbulent and its azimuthal ...
    • Influence of pressure gradients on wall pressure beneath a turbulent boundary layer 
      Article dans une revue avec comité de lecture
      COHEN, Elie; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2018)
      This study investigates the effects of a pressure gradient on the wall pressure beneath equilibrium turbulent boundary layers. Excitation of the walls of a vehicle by turbulent boundary layers indeed constitutes a major ...
    • Silent inflow condition for turbulent boundary layers 
      Article dans une revue avec comité de lecture
      ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (American Physical Society, 2017)
      The generation of a turbulent inflow is a tricky problem. In the framework of aeroacoustics, another important constraint is that the numerical strategy used to reach a turbulent state induces a spurious noise which is ...
    • Closed-loop control of a free shear flow: a framework using the parabolized stability equations 
      Article dans une revue avec comité de lecture
      SASAKI, Kenzo; TISSOT, Gilles; CAVALIERI, André V. G.; SILVESTRE, Flávio J.; JORDAN, Peter; ccBIAU, Damien (Springer Verlag, 2018)
      In this study the parabolized stability equations (PSE) are used to build reduced-order-models (ROMs) given in terms of frequency and time-domain transfer functions (TFs) for application in closed-loop control. The control ...
