    • 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 ...
    • Direct Numerical Simulation of a hypersonic boundary layer in chemical non-equilibrium 
      Communication avec acte
      ccPASSIATORE, Donatella; ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccPASCAZIO, Giuseppe (3AF, Association Aéronautique et Astronautique de France, 2021-04)
      The influence of high-enthalpy effects in hypersonic, spatially developing boundary layers is investigated by means of direct numerical simulations. The flow of a reacting mixture of nitrogen and oxygen over a flat plate ...
    • A high-order scheme for the numerical simulation of high-enthalpy hypersonic flows 
      Communication avec acte
      ccPASSIATORE, Donatella; ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccPASCAZIO, Giuseppe (ICCFD, 2022-07)
      A high-order shock-capturing finite-difference scheme for scale-resolving numerical simulations of hypersonic high-enthalpy flows, involving thermal non-equilibrium effects, is presented. The suitability of the numerical ...
    • Numerical investigation of hypersonic turbulent boundary layers with high-temperature effects 
      Communication avec acte
      ccPASSIATORE, Donatella; ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccPASCAZIO, Giuseppe (Council of the Aeronautical Sciences, 2022-11)
      A hypersonic turbulent boundary layer over a flat plate is numerically investigated. The large Mach number and temperature values in the freestream (M e = 12.48 and T e = 594.3 K, respectively) lead to a high-enthalpy ...
    • A priori tests of turbulence models for compressible flows 
      Communication avec acte
      CANNICI, Aron; ccPASSIATORE, Donatella; ccSCIACOVELLI, Luca; ccCINNELLA, Paola (3AF, Association Aéronautique et Astronautique de France, 2023-03)
      The present work reports the results of a priori tests of Reynolds-Averaged Navier–Stokes (RANS) models based on Direct Numerical Simulations (DNS) data of zero-pressure-gradient flat-plate turbulent boundary layers. The ...
