    • 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 ...
    • External Laminar Boundary Layer Simulations Using a High-Fidelity Wall-Modeling Approach 
      Conférence invitée
      VIANA DAURICIO, Eron Tiago; ccJUNQUEIRA JUNIOR, Carlos; FEROLLA DE ABREU, Diego; AZEVEDO, João Luiz F. (ABCM, 2022-11)
      Wall-Modeled Large Eddy Simulation (WMLES) is a well-stablished technique for obtaining high-fidelity solutions of turbulent, high Reynolds number flows, with reasonably acceptable computational costs. However, for external ...
    • Self-similar temporal turbulent boundary layer flow 
      Article dans une revue avec comité de lecture
      ccBIAU, Damien (Elsevier BV, 2023-01)
      Direct numerical simulations of temporally evolving boundary layer flows are considered with solutions restricted to self-similar profiles. A new set of modified Navier–Stokes equations is solved with periodic boundary ...
    • Flow in a weakly curved square duct: Assessment and extension of Dean's model 
      Article dans une revue avec comité de lecture
      ccRIGO, Leonardo; ccBIAU, Damien; ccGLOERFELT, Xavier (American Physical Society (APS), 2021-02)
      The simplified model by W. R. Dean, based on a low-curvature assumption, provided an early understanding of the laminar flow in curved ducts. However, most of the following studies relied on computer simulations of the ...
    • Global stability, sensitivity and passive control of low-Reynolds-number flows around NACA 4412 swept wings 
      Article dans une revue avec comité de lecture
      ccNASTRO, Gabriele; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe; ccPASSAGGIA, Pierre-Yves; ccMAZELLIER, Nicolas (Cambridge University Press, 2023-01)
      The stability and sensitivity of two- and three-dimensional global modes developing on steady spanwise-homogeneous laminar separated flows around NACA 4412 swept wings are numerically investigated for different Reynolds ...
