    • 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 ...
    • On elastic gaps in strain gradient plasticity: 3D discrete dislocation dynamics investigation 
      Article dans une revue avec comité de lecture
      AMOUZOU-ADOUN, Yaovi Armand; ccJEBAHI, Mohamed; FIVEL, Marc; FOREST, Samuel; LECOMTE, Jean-Sebastien; SCHUMAN, Christophe; ccABED-MERAIM, Farid  (Elsevier BV, 2023-04)
      Although presenting attractive features in dealing with small-scale size effects, strain gradient plasticity (SGP) theories can lead to uncommon phenomena for some boundary value problems. Almost all non-incremental ...
    • 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 ...
    • Design and control of a new electrostrictive polymer based continuum actuator for endoscopic robot 
      Article dans une revue avec comité de lecture
      ccJACQUEMIN, Quentin; SUN, Q; ccTHUAU, Damien; ccTENCE-GIRAULT, Sylvie; ccDOIZI, Steeve; ccTRAXER, Olivier; ccMECHBAL, Nazih; ccMONTEIRO, Eric (SAGE Publications, 2022-12)
      Minimally Invasive Surgery (MIS) consists of the insertion of a flexible endoscope into the patient body through natural orifices. Over the past few decades, the growing interest in microelectromechanical systems (MEMS) ...
