    • Global stability analysis of lifted diffusion flames 
      Article dans une revue avec comité de lecture
      MANCINI, C.; FARANO, Mirko; DE PALMA, Pietro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (Elsevier, 2017)
      This work describes the development of a method for the global hydrodynamic stability analysis of diffusion flames. The low-Machnumber (LMN) Navier–Stokes (NS) equations for reacting flows are solved together with a transport ...
    • A Priori Tests of RANS Models for Turbulent Channel Flows of a Dense Gas 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Springer Verlag (Germany), 2018)
      Dense gas effects, encountered in many engineering applications, lead to unconventional variations of the thermodynamic and transport properties in the supersonic flow regime, which in turn are responsible for considerable ...
    • Epoxy/amine reactive systems for composites materials and their thermomechanical properties 
      Chapitre d'ouvrage scientifique
      NONY, Fabien; FARZANEH, Sedigheh; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph; ccKHELLADI, Sofiane (Elsevier, 2015)
      In this chapter, epoxy/amines systems are studied during their synthesis and once they are synthesized. In the first part of this chapter, the different cross-linking mechanisms and their kinetics are presented. Then the ...
    • Linear stability of optimal streaks in the log-layer of turbulent channel flows 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric (American Institute of Physics, 2015)
      The importance of secondary instability of streaks for the generation of vortical struc-tures attached to the wall in the logarithmic region of turbulent channels is studied. Thestreaks and their linear instability are ...
    • Permeability models affecting nonlinear stability in the asymptotic suction boundary layer: the Forchheimer versus the Darcy model 
      Article dans une revue avec comité de lecture
      WEDIN, Håkan; CHERUBINI, Stefania (IOP Publishing, 2016)
      The asymptotic suction boundary layer (ASBL) is used for studying two permeability models, namely the Darcy and the Forchheimer model, the latter being more physically correct according to the literature. The term that ...
    • Invariant solutions in a channel flow using a minimal restricted nonlinear model 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric (Elsevier Masson, 2017)
      Simulations using a Restricted Nonlinear (RNL) system, where mean flow distortion resulting from Reynolds stress feedback regenerates rolls, is applied in a channel flow under subcritical conditions. This quasi-linear ...
    • 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 ...
