    • 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 ...
    • Conventional rotational molding process and aerodynamic characteristics of an axial-flow hollow blades rotor 
      Article dans une revue avec comité de lecture
      LUCAS, Albert; DANLOS, Amélie; SHIRINBAYAN, Mohammadali; MOTAHARINEJAD, Vajihe; PARIDAENS, Richard; ccBENFRIHA, Khaled; ccTCHARKHTCHI, Abbas; ccBAKIR, Farid (Springer Verlag, 2019)
      n this work, the rotational molding process is developed to manufacture in one piece an axial-flow turbomachine rotor with hollow blades. Giving to our knowledge, this process has never been employed in the making of these ...
    • 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 ...
    • 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 ...
    • Dense gas effects in inviscid homogeneous isotropic turbulence 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; CONTENT, C.; GRASSO, Francesco; ccSCIACOVELLI, Luca (Cambridge University Press (CUP), 2016)
      A detailed numerical study of the influence of dense gas effects on the large-scale dynamics of decaying homogeneous isotropic turbulence is carried out by using the van der Waals gas model. More specifically, we focus on ...
    • 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 ...
