    • 1/f noise and long-term memory of coherent structures in a turbulent shear flow 
      Article dans une revue avec comité de lecture
      GISSINGER, C.; FAUVE, S.; ccPEREIRA, Michaël (American Physical Society (APS), 2019)
      A shear flow of liquid metal (Galinstan) is driven in an annular channel by counter-rotating traveling magnetic fields imposed at the endcaps. When the traveling velocities are large, the flow is turbulent and its azimuthal ...
    • A naturally anti-diffusive compressible two phases Kapila model with boundedness preservation coupled to a high order finite volume solver 
      Article dans une revue avec comité de lecture
      SPECKLIN, Mathieu; ccDELIGANT, Michael; ccKHELLADI, Sofiane (ELSEVIER, 2015)
      This paper presents a two phases flow model combined with a high order finite volume solver on unstructured mesh. The solver is highly conservative and preserves the sharpness of the interface without any reconstruction. ...
    • Silent inflow condition for turbulent boundary layers 
      Article dans une revue avec comité de lecture
      ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (American Physical Society, 2017)
      The generation of a turbulent inflow is a tricky problem. In the framework of aeroacoustics, another important constraint is that the numerical strategy used to reach a turbulent state induces a spurious noise which is ...
    • 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 ...
    • PySINDy: A Python package for the sparse identification of nonlinear dynamical systems from data 
      Article dans une revue avec comité de lecture
      DE SILVA, Brian; CHAMPION, Kathleen; QUADE, Markus; KUTZ, J. Nathan; BRUNTON, Steven; ccLOISEAU, Jean-Christophe (Open Journals, 2020)
      Scientists have long quantified empirical observations by developing mathematical models that characterize the observations, have some measure of interpretability, and are capable of making predictions. Dynamical systems ...
    • 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 ...
    • 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 ...
