    • Effects of axial rectangular groove on turbulent Taylor-Couette flow from analysis of experimental data 
      Article dans une revue avec comité de lecture
      SODJAVI, Kodjovi; ccRAVELET, Florent; ccBAKIR, Farid (Elsevier, 2018)
      The relationship between a rough or structured surface topology and its hydraulic resistance was analysed in the case of fully turbulent Taylor-Couette flow at fixed radii ratio η = 0.9375 and for Reynolds numbers Re i ...
    • Attached cavitation in laminar separations within a transition to unsteadiness 
      Article dans une revue avec comité de lecture
      CROCI, Kilian; DANLOS, Amélie; BARAST, Luc; ccROBINET, Jean-Christophe; ccRAVELET, Florent (American Institute of Physics, 2019)
      Attached sheet cavitation is usually observed in turbulent water flows within small laminar separation bubbles which can provide favorable conditions for inception and attachment of cavities. In the present study, viscous ...
    • Small-scale dynamics of dense gas compressible homogeneous isotropic turbulence 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; GRASSO, Francesco; ccSCIACOVELLI, Luca (Cambridge University Press (CUP), 2017)
      The present paper investigates the influence of dense gases governed by complex equations of state on the dynamics of homogeneous isotropic turbulence. In particular, we investigate how differences due to the complex ...
    • 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 ...
