    • Bayesian model-scenario averaged predictions of compressor cascade flows under uncertain turbulence models 
      Article dans une revue avec comité de lecture
      ccDE ZORDO-BANLIAT, Maximilien; MERLE, Xavier; ccDERGHAM, Grégory; ccCINNELLA, Paola (Elsevier BV, 2020-04)
      The Reynolds-Averaged Navier-Stokes (RANS) equations represent the computational workhorse for engineering design, despite their numerous flaws. Improving and quantifying the uncertainties associated with RANS models is ...
    • CFD-driven symbolic identification of algebraic Reynolds-stress models 
      Article dans une revue avec comité de lecture
      ccBEN HASSAN SAIDI, Ismaïl; ccSCHMELZER, Martin; ccCINNELLA, Paola; GRASSO, Francesco (Elsevier Inc., 2022-02)
      Reynolds-stress models (EARSM) from high-fidelity data is developed building on the frozen-training SpaRTA algorithm of [1]. Corrections for the Reynolds stress tensor and the production of transported turbulent quantities ...
    • DNS of turbulent flows of dense gases 
      Article dans une revue avec comité de lecture
      ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccGLOERFELT, Xavier; GRASSO, Francesco (IOP Publishing, 2017-04)
      The influence of dense gas effects on compressible turbulence is investigated by means of numerical simulations of the decay of compressible homogeneous isotropic turbulence (CHIT) and of supersonic turbulent flows through ...
    • Analysis of Dense Gas Effects in Compressible Turbulent Channel Flows 
      Communication avec acte
      ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccGLOERFELT, Xavier (Springer International Publishing, 2019-02-02)
      In this work we investigate the influence of dense gas effects on compressible wall-bounded turbulence. Turbulent flows of dense gases represent a research field of great importance for a wide range of applications in ...
    • Numerical Investigation of Supersonic Dense-Gas Boundary Layers 
      Communication avec acte
      ccSCIACOVELLI, Luca; ccPASSIATORE, Donatella; ccGLOERFELT, Xavier; ccCINNELLA, Paola; GRASSO, Francesco (Springer International Publishing, 2020-07)
      A study of dense-gas effects on the laminar, transitional and turbulent characteristics of boundary layer flows is conducted. The laminar similarity solution shows that temperature variations are small due to the high ...
    • Numerical Investigation of Hypersonic Boundary Layers of Perfect and Dense Gases 
      Communication avec acte
      ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier; ccCINNELLA, Paola; GRASSO, Francesco (Springer International Publishing, 2020-05)
      Hypersonic turbulent boundary layers (HTBL) at Mach number M =6 of a dense gas (PP11) and a perfect gas (air) are investigated by means of Direct Numerical Simulations (DNS), from the laminar to fully turbulent state. The ...
    • Direct Numerical Simulation of hypersonic boundary layers in chemical non-equilibrium 
      Communication sans acte
      ccPASSIATORE, Donatella; ccSCIACOVELLI, Luca; ccPASCAZIO, Giuseppe; ccCINNELLA, Paola (IUTAM, International Union of Theoretical and Applied Mechanics, 2021-08)
      The influence of high-temperature effects on compressible wall-bounded turbulence is investigated by means of a direct numerical simulation of a hypersonic, chemically out-of-equilibrium, turbulent boundary layer. The ...
