    • Thermal aging of High Tenacity Polyvinyl Alcohol yarns 
      Article dans une revue avec comité de lecture
      BIAN, Yan; ARESSY, Matthieu; ccCOLIN, Xavier (Elsevier, 2020)
      A both multiscale and multi-techniques approach was developed to characterize the thermal aging in air at 70, 90, 100 and 120 °C of High Tenacity Polyvinyl Alcohol (HT-PVAl) yarns, and to elucidate the consequences of ...
    • A high-order time formulation of the RBC schemes for unsteady compressible Euler equations 
      Article dans une revue avec comité de lecture
      LERAT, Alain (Elsevier, 2015)
      Residual-Based Compact (RBC) schemes can approximate the compressible Euler equations with a high space-accuracy on a very compact stencil. For instance on a 2-D Cartesian mesh, the 5th and 7th-order accuracy can be reached ...
    • On the scalability of CFD tool for supersonic jet flow configurations 
      Article dans une revue avec comité de lecture
      JUNQUEIRA-JUNIOR, Carlos; AZEVEDO, João Luiz F.; PANETTA, Jairo; WOLF, William R.; YAMOUNI, Sami (Elsevier, 2020)
      New regulations are imposing noise emissions limitations for the aviation industry which are pushing researchers and engineers to invest efforts in studying the aeroacoustics phenomena. Following this trend, an in-house ...
    • Degradation assessment of polyethylene-based material through electrical and chemical-physical analyses 
      Article dans une revue avec comité de lecture
      SURACI, Simone Vincenzo; FABIANI, Davide; MAZZOCCHETTI, Laura; GIORGINI, Loris (MDPI, 2020)
      The usability of any material hinges upon its stability over time. One of the major concerns, focusing on polymeric materials, is the degradation they face during their service life. The degradation mechanisms are deeply ...
    • Space–time dynamics of optimal wavepackets for streaks in a channel entrance flow 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; CADIOU, A.; LE PENVEN, L.; DI PIERRO, B.; BUFFAT, M. (Cambridge University Press (CUP), 2018)
      The laminar–turbulent transition of a plane channel entrance flow is revisited using global linear optimization analyses and direct numerical simulations. The investigated case corresponds to uniform upstream velocity ...
    • Development of a third-order accurate vorticity confinement scheme 
      Article dans une revue avec comité de lecture
      COSTES, M.; PETROPOULOS, I.; ccCINNELLA, Paola (ELSEVIER, 2016)
      A new 3rd-order Vorticity Confinement scheme is presented as an extension of the original VC2 scheme developed by Steinhofffor the resolution of the fluid dynamic equations. The theoretical developments are explained, and ...
    • High-order implicit residual smoothing time scheme for direct and large eddy simulations of compressible flows 
      Article dans une revue avec comité de lecture
      ccCINNELLA, Paola; CONTENT, C. (Elsevier, 2016)
      Restrictions on the maximum allowable time step of explicit time integration methods for direct and large eddy simulations of compressible turbulent flows at high Reynolds numbers can be very severe, because of the extremely ...
