    • Investigation of high-order methods in large-eddy simulation of separated flow in a channel with periodic constrictions 
      Chapitre d'ouvrage scientifique
      CINNELLA, Paola; ccGLOERFELT, Xavier (Springer, 2018)
      In large-eddy simulations (LES), only the dynamics of large scales is computed and the effect of smaller scales is modelled. Scale separation is however difficult to establish since the low-pass filtering arises from a ...
    • 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 ...
    • Sparse reduced-order modelling: sensor-based dynamics to full-state estimation 
      Article dans une revue avec comité de lecture
      NOACK, Bernd R.; BRUNTON, Steven L.; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2018)
      We propose a general dynamic reduced-order modelling framework for typical experimental data: time-resolved sensor data and optional non-time-resolved particle image velocimetry (PIV) snapshots. This framework can be ...
    • Thermal aging influence on the damage mechanisms of fully recycled composite-reinforced polypropylene/polyethylene blend 
      Article dans une revue avec comité de lecture
      MEFTAH, Hassen; TAMBOURA, Sahbi; BENDALY, Hachmi; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph (Wiley, 2019)
      The main aim of this work is to study the effect of thermal aging on damage mechanisms of a totally recycled composite. The studied material was elaborated by injection molding from a mixture of both recycled matrix ...
    • NUMERICAL MODELING OF UNSTABLE FLOWS IN CONDUCTS WITH VARIABLE GEOMETRY 
      Article dans une revue avec comité de lecture
      RAMOUL, Sami; FOURAR, Ali; MASSOUH, Fawaz (Politechnica University of Bucharest, 2018)
      Changes in the system flow of a fluid in a conduct often cause sudden changes in pressure and give rise to so-called unstable flows. So, the study of the phenomenon of unstable flows aims to determine ...
    • 3D global optimal forcing and response of the supersonic boundary layer 
      Article dans une revue avec comité de lecture
      CHASSAING, Jean-Camille; SAGAUT, P.; BUGEAT, Benjamin; ccROBINET, Jean-Christophe (Elsevier, 2019)
      3D optimal forcing and response of a 2D supersonic boundary layer are obtained by computing the largest singular value and the associated singular vectors of the global resolvent matrix. This approach allows to take into ...
    • Global stability analysis of 3D micro-combustion model 
      Article dans une revue avec comité de lecture
      BUCCI, Michele Alessandro; CHIBBARO, Sergio; ccROBINET, Jean-Christophe (Elsevier, 2016)
      We report on the linear stability of micro-combustion in pipe, where two instabilities manifest at high and low flow-rates. The combustion of a stoichiometric methane/air premixed mixture has been numerically investigated ...
