    • 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 ...
    • Hydrokinetic propeller turbines. How many blades? 
      Article dans une revue avec comité de lecture
      BRASIL JUNIOR, Antonio Cesar Pinho; MENDES, Rafael C. F.; LACROIX, Julian; NOGUERA, Ricardo; OLIVEIRA, Taygoara F. (Centro Nacional de Referência em Pequenas Centrais Hidrelétricas, UNIFEI, 2017)
      A design study of propeller hydrokinetic turbines is presented. The main objective is to evaluate the optimized geometry for horizontal axis hydrokinetic turbines, take into account the runner design with a different number ...
    • 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 ...
    • 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 ...
    • 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. ...
    • Bayesian Predictions of Reynolds-Averaged Navier–Stokes Uncertainties Using Maximum a Posteriori Estimates 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; SCHMELZER, Martin; EDELING, Wouter Nico (American Institute of Aeronautics and Astronautics, 2018)
      Computational fluid dynamics analyses of high-Reynolds-number flows mostly rely on the Reynolds-averaged Navier–Stokes equations. The associated closure models are based on multiple simplifying assumptions and involve ...
