    • Recent Progress in High-Order Residual-Based Compact Schemes for Compressible Flow Simulations: Toward Scale-Resolving Simulations and Complex Geometries 
      Ouvrage scientifique
      CINNELLA, Paola; GRIMICH, Karim; LERAT, Alain; OUTTIER, P. Y. (Springer International Publishing, 2015)
      Recent developments about the extension of high-order Residual-Based Compact schemes to unsteady flows and complex configurations are discussed, with application to scale-resolving simulations and complex turbomachinery flows.
    • Automatic Hybrid RANS/LES Strategy for Industrial CFD 
      Chapitre d'ouvrage scientifique
      PONT, Grégoire; CINNELLA, Paola; BRENNER, Pierre; ccROBINET, Jean-Christophe (Springer International Publishing, 2015)
      An automatic HRL (Hybrid RANS/LES) strategy is investigated in FLUSEPA, a finite-volume solver developed by Airbus Defense and Space. A HRL turbulence model is coupled to a high-order hybrid numerical approximation method. ...
    • Robust prediction of dense gas flows under uncertain thermodynamic models 
      Article dans une revue avec comité de lecture
      MERLE, Xavier; CINNELLA, Paola (Elsevier, 2019)
      A Bayesian approach is developed to quantify uncertainties associated with the thermodynamic models used for the simulation of dense gas flows, i.e. flows of gases characterized by complex molecules of moderate to high ...
    • Toward an improved wall treatment for multiple-correction k-exact schemes 
      Communication avec acte
      MENASRIA, Amandine; BRENNER, Pierre; CINNELLA, Paola; PONT, Grégoire (American Institute of Aeronautics and Astronautics, 2018)
      Improved wall boundary treatments are investigated for a family of high-order Godunovtype finite volume schemes based on k-exact polynomial reconstructions in each cell of the primitive variables, via a successive corrections ...
    • Simplex-stochastic collocation method with improved scalability 
      Article dans une revue avec comité de lecture
      EDELING, Wouter Nico; DWIGHT, Richard P.; CINNELLA, Paola (Elsevier, 2016)
      The Simplex-Stochastic Collocation (SSC) method is a robust tool used to propagate uncertain input distributions through a computer code. However, it becomes prohibitively expensive for problems with dimensions higher than ...
    • On wall pressure fluctuations and their coupling with vortex dynamicsin a separate d–reattache d turbulent flow over a blunt flat plate 
      Article dans une revue avec comité de lecture
      TENAUD, C; PODVIN, B; FRAIGNEAU, Y; ccDARU, Virginie (Elsevier, 2016)
      This study deals with the numerical predictions through Large-Eddy Simulation ( LES ) of the separated–reattached turbulent flow over a blunt flat plate for analyzing main coherent structure features and theirrelation to ...
    • Strong scaling of numerical solver for supersonic jet flow configurations 
      Article dans une revue avec comité de lecture
      JUNQUEIRA-JUNIOR, Carlos; AZEVEDO, João Luiz F.; PANETTA, Jairo; WOLF, William R.; YAMOUNI, Sami (Springer Verlag, 2019)
      Acoustics loads are rocket design constraints which push researches and engineers to invest efforts in the aeroacoustics phenomena which is present on launch vehicles. Therefore, an in-house computational fluid dynamics ...
