    • Dense-gas effects on compressible boundary-layer stability 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; GRASSO, Francesco; ccROBINET, Jean-Christophe; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2020)
      A study of dense-gas effects on the stability of compressible boundary-layer flows is conducted. From the laminar similarity solution, the temperature variations are small due to the high specific heat of dense gases, ...
    • Invariant solutions in a channel flow using a minimal restricted nonlinear model 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric (Elsevier Masson, 2017)
      Simulations using a Restricted Nonlinear (RNL) system, where mean flow distortion resulting from Reynolds stress feedback regenerates rolls, is applied in a channel flow under subcritical conditions. This quasi-linear ...
    • Development and analysis of high-order vorticity confinement schemes 
      Article dans une revue avec comité de lecture
      PETROPOULOS, I.; COSTES, M.; CINNELLA, Paola (ELSEVIER, 2017)
      High-order extensions of the Vorticity Confinement (VC) method are developed for the accurate com- putation of vortical flows, following the VC2 conservative formulation of Steinhoff. First, a high-order formulation of VC ...
    • Aeroacoustic Study of the Interaction of a Rotating Blade with a Batchelor Vortex 
      Article dans une revue avec comité de lecture
      ZEHNER, Paul; FALISSARD, Fabrice; ccGLOERFELT, Xavier (American Institute of Aeronautics and Astronautics, 2018)
      The aeroacoustic response of the orthogonal interaction of a rotating blade with an isolated Batchelor vortex is studied by means of numerical simulation. The relative influence of the vortex tangential and axial velocity ...
    • Multiphase smoothed particle hydrodynamics approach for modeling soil–water interactions 
      Article dans une revue avec comité de lecture
      KRIMI, Abdelkader; NOGUEIRA, Xesús; ATA, Riadh; REZOUG, Mehdi; ccDELIGANT, Michael; ccKHELLADI, Sofiane (Elsevier, 2018)
      In this work, a weakly compressible smoothed particle hydrodynamics (WCSPH) multiphase model is developed. The model is able to deal with soil-water interactions coupled in a strong and natural form. A Regularized Bingham ...
    • A Higher-Order Chimera Method for Finite Volume Schemes 
      Article dans une revue avec comité de lecture
      RAMÍREZ, Luis; NOGUEIRA, Xesús; OURO, Pablo; NAVARRINA, Fermín; COLOMINAS, Ignasi; ccKHELLADI, Sofiane (Springer Verlag, 2017)
      In this work a higher-order accurate finite volume method for the resolution of the Euler/Navier–Stokes equations using Chimera grid techniques is presented. The formulation is based on the use of Moving Least Squares ...
    • Time-Stepping and Krylov Method for large scale instability problems 
      Chapitre d'ouvrage scientifique
      BUCCI, Michele Alessandro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Springer, 2018)
      With the ever increasing computational power available and the development of high-performances computing, investigating the properties of realistic very large-scale nonlinear dynamical systems has become reachable. It ...
