    • Multiple-correction hybrid k -exact schemes for high-order compressible RANS-LES simulations on fully unstructured grids 
      Article dans une revue avec comité de lecture
      PONT, Grégoire; BRENNER, Pierre; CINNELLA, Paola; MAUGARS, Bruno; ccROBINET, Jean-Christophe (Elsevier, 2017)
      A Godunov's type unstructured finite volume method suitable for highly compressible turbulent scale-resolving simulations around complex geometries is constructed by using a successive correction technique. First, a family ...
    • Data-Free and Data-Driven RANS Predictions with Quantified Uncertainty 
      Article dans une revue avec comité de lecture
      EDELING, Wouter Nico; IACCARINO, Gianluca; CINNELLA, Paola (Springer Verlag (Germany), 2017)
      For the purpose of estimating the epistemic model-form uncertainty in Reynolds-Averaged Navier-Stokes closures, we propose two transport equations to locally perturb the Reynolds stress tensor of a given baseline eddy-viscosity ...
    • Model-form and predictive uncertainty quantification in linear aeroelasticity 
      Article dans une revue avec comité de lecture
      NITSCHKE, Christian T.; CINNELLA, Paola; LUCOR, Didier; CHASSAING, Jean-Camille (Elsevier, 2017)
      In this work, Bayesian techniques are employed to quantify model-form and predictive uncertainty in the linear behavior of an elastically mounted airfoil undergoing pitching and plunging motions. The Bayesian model averaging ...
    • Large Eddy Simulation Requirements for the Flow over Periodic Hills 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; ccGLOERFELT, Xavier (Springer Verlag (Germany), 2019)
      Large eddy simulations are carried out for flows in a channel with streamwise-periodic constrictions, a well-documented benchmark case to study turbulent flow separation from a curved surface. Resolution criteria such as ...
    • Quantification of model uncertainty in RANS simulations: A review 
      Article dans une revue avec comité de lecture
      XIAO, Heng; CINNELLA, Paola (Elsevier, 2019)
      In computational fluid dynamics simulations of industrial flows, models based on the Reynolds-averaged Navier–Stokes (RANS) equations are expected to play an important role in decades to come. However, model uncertainties ...
    • Direct numerical simulations of supersonic turbulent channel flows of dense gases 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2017)
      The influence of dense-gas effects on compressible wall-bounded turbulence is investigated by means of direct numerical simulations of supersonic turbulent channel flows. Results are obtained for PP11, a heavy fluorocarbon ...
    • Sensitivity of Supersonic ORC Turbine Injector Designs to Fluctuating Operating Conditions 
      Communication avec acte
      BUFI, Elio Antonio; CINNELLA, Paola; MERLE, Xavier; CINNELLA, Paola (ASME, 2015)
      The design of an efficient organic rankine cycle (ORC) expander needs to take properly into account strong real gas effects that may occur in given ranges of operating conditions, which can also be highly variable. In this ...
