    • 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 ...
    • Shock-wave/boundary layer interaction at high enthalpies 
      Communication avec acte
      ccPASSIATORE, Donatella; ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccPASCAZIO, Giuseppe (3AF, Association Aéronautique et Astronautique de France, 2023-03-29)
      The dynamics of a shock wave impinging on a freestream-perturbed high-enthalpy boundary layer is investigated by means of direct numerical simulation. The oblique shock impacts on a cooled flat-plate boundary layer with ...
    • Numerical investigation of sheet cavitation over a 3-D venturi configuration 
      Communication avec acte
      GOUIN, Camille; ccJUNQUEIRA JUNIOR, Carlos; ccGONCALVES, Eric; ccROBINET, Jean-Christophe (The Society of Naval Architects of Korea (SNAK), 2021-05)
      Sheet cavitation appears in many hydraulic applications and can lead to technical issues. Numerical simulation is a pertinent way to study the phenomenon. A numerical tool based on 1-fluid compressible RANS equations with ...
    • Large-eddy simulations of turbulent compressible supersonic jet flows using discontinuous Galerkin methods 
      Communication avec acte
      F. ABREU, Diego; ccJUNQUEIRA JUNIOR, Carlos; ccDAURICIO, Eron; F. AZEVEDO, João Luiz (Scipedia S.L., 2022-06)
      In this work, a discontinuous Galerkin scheme is employed to perform the simulations of supersonic jet flows. A total of four simulations are performed with different meshes and order of accuracy. The number of degrees of ...
