    • Investigation of the dynamics in separated turbulent flow 
      Article dans une revue avec comité de lecture
      FADLA, Fawzi; ALIZARD, Frédéric; KEIRSBULCK, Laurent; LAVAL, Jean-Philippe; FOUCAUT, Jean-Marc; CHOVET, Camila; LIPPERT, Marc; ccROBINET, Jean-Christophe (Elsevier, 2019)
      Dynamical behavior of the turbulent channel flow separation induced by a wall-mounted two-dimensional bump is studied, with an emphasis on unsteadiness characteristics of vortical motions evolving in the separated flow. ...
    • A synthetic forcing to trigger laminar-turbulent transition in parallel wall bounded flows via receptivity 
      Article dans une revue avec comité de lecture
      PICELLA, Francesco; BUCCI, Michele Alessandro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (Elsevier, 2019)
      Research on laminar-turbulent transition of wall-bounded parallel flows has usually focused on controlled scenarios where transition is triggered by perturbations having simple shapes and spectra. These disturbances strongly ...
    • Subcritical transition scenarios via linear and nonlinear localized optimal perturbations in plane Poiseuille flow 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (IOP Publishing, 2016)
      Subcritical transition in plane Poiseuilleflow is investigated by means of aLagrange-multiplier direct-adjoint optimization procedure with the aim offinding localized three-dimensional perturbations optimally growing in a ...
    • Kinetics of chlorine-induced polyethylene degradation in water pipes 
      Article dans une revue avec comité de lecture
      DEVILLIERS, Clémence; LAIARINANDRASANA, Lucien; OBERTI, Sandrine; GAUDICHET-MAURIN, Emmanuelle; ccFAYOLLE, Bruno (Elsevier, 2011)
      The presence of chlorine in drinking water supplies in many countries creates the undesirable side effect of causing a relatively under investigated degree of polymer degradation in the polyethylene pipes used for transport. ...
    • Modelling of thermal oxidation of phosphite stabilized polyethylene 
      Article dans une revue avec comité de lecture
      DJOUANI, Fatma; VERDU, Jacques; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2011)
      The thermal oxidation behaviour of polyethylene films stabilized by various weight ratios of organophosphites (Irgafos 168) has been studied at selected temperatures. The duration of the induction period was found to ...
    • Ring tests on high density polyethylene: Full investigation assisted by finite element modeling 
      Article dans une revue avec comité de lecture
      LAIARINANDRASANA, Lucien; DEVILLIERS, Clémence; OBERTI, Sandrine.; GAUDICHET, E; LUCATELLI, Jean Marc; ccFAYOLLE, Bruno (Elsevier, 2011)
      In order to characterize the mechanical behavior of HDPE pipes, the ASTM D 2290-04 standard recommends carrying out tensile tests on notched rings, cut out from the pipe. This very simple test is also utilized to investigate ...
    • A kinetic model for predicting PET macromolecular changes during its mechanical recycling 
      Article dans une revue avec comité de lecture
      NAÏT-ALI, Linda K.; BERGERET, Anne; ccCOLIN, Xavier (EDP Sciences, 2011)
      The rheometer cavity has been used to analyse, in carefully controlled exposure conditions, the macromolecular changes generated by the mechanical recycling of PET during its extrusion. Isothermal ageing tests at 280 °C, ...
