    • Effect of UV-aging on the mechanical and fracture behavior of low density polyethylene 
      Article dans une revue avec comité de lecture
      RODRIGUEZ, Ana K.; MANSOOR, Bilal; AYOUB, Georges; BENZERGA, Amine A.; ccCOLIN, Xavier (Elsevier, 2020)
      In polyethylene, a transient, oxidation-induced strengthening is often observed over a narrow range of UV radiation dose. In addition, plastic deformation may not be volume-preserving due to cavitation. Here, we employ a ...
    • Simulation of Viscous Fingering Instability by the Lattice Boltzmann Method 
      Communication avec acte
      VIENNE, Lucien; MARIE, Simon; GRASSO, Francesco (American Institute of Aeronautics and Astronautics, 2019)
      The viscous fingering instability is successfully simulated within a lattice Boltzmann framework. Each species of the mixture is governed by its own kinetic equation and a force takes into account the diffusion between ...
    • Lattice Boltzmann method for miscible gases: A forcing-term approach 
      Article dans une revue avec comité de lecture
      VIENNE, Lucien; MARIÉ, Simon; GRASSO, Francesco (American Physical Society (APS), 2019)
      A lattice Boltzmann method for miscible gases is presented. In this model, the standard lattice Boltzmann method is employed for each species composing the mixture. Diffusion interaction among species is taken into account ...
    • An efficient high-order compact scheme for the unsteady compressible Euler and Navier–Stokes equations 
      Article dans une revue avec comité de lecture
      LERAT, Alain (Elsevier, 2016)
      Residual-Based Compact (RBC) schemes approximate the 3-D compressible Euler equations with a 5th- or 7th-order accuracy on a 5 × 5 × 5-point stencil and capture shocks pretty well without correction. For unsteady flows ...
    • Multiscale thermal study of virgin and aged polyphenylene sulfide reinforced by glass fiber 
      Article dans une revue avec comité de lecture
      ZUO, Peiyuan; ccSHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph; ccBAKIR, Farid (Wiley, 2020)
      In this study, virgin and thermal aged PPS samples were prepared and tested using different techniques such as thermogravimetric analysis (TGA), coupled TGA–Fourier transform infrared spectroscopy (FTIR), and FTIR as well ...
    • On the linear receptivity of trailing vortices 
      Article dans une revue avec comité de lecture
      BÖLLE, Tobias; BRION, Vincent; SIPP, Denis; JACQUIN, Laurent; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2020)
      The present work investigates the excitation process by which free-stream disturbances are transformed into vortex-core perturbations. This problem of receptivity is modelled in terms of the resolvent in frequency space ...
    • Weakly nonlinear optimal perturbations 
      Article dans une revue avec comité de lecture
      PRALITS, Jan O.; BOTTARO, Alessandro; CHERUBINI, Stefania (Cambridge University Press (CUP), 2015)
      A simple approach is described for computing spatially extended, weakly nonlinear optimal disturbances, suitable for maintaining a disturbance-regeneration cycle in a simple shear flow. Weakly nonlinear optimals, computed ...
