    • 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 ...
    • 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 ...
    • On the miscibility of PVDF/PMMA polymer blends: Thermodynamics, experimental and numerical investigations 
      Article dans une revue avec comité de lecture
      AID, Sara; EDDHAHAK, Anissa; ORTEGA, Zaida; CHAABANI, Sana; ccTCHARKHTCHI, Abbas; ccKHELLADI, Sofiane (Elsevier, 2019)
      In this paper the miscibility of PVDF/PMMA blends was studied using different approaches: experimental tests, thermodynamics and numerical simulation. The first part of this study is devoted to the experimental work and ...
    • High-Order Hybrid RANS/LES Strategy for Industrial Applications 
      Chapitre d'ouvrage scientifique
      PONT, G.; CINNELLA, Paola; BRENNER, Pierre; ccROBINET, Jean-Christophe (Springer, 2017)
      Turbulent flows of industrial interest are often dominated by large turbulent structures. A typical example is provided by launcher base flows, combining one or more extended and interacting separated regions with strong ...
    • Optimal transient growth in compressible turbulent boundary layers 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; PIROZZOLI, Sergio; BERNARDINI, Matteo; GRASSO, Francesco (Cambridge University Press (CUP), 2015)
      The structure of zero-pressure-gradient compressible turbulent boundary layers is analysed using the tools of optimal transient growth theory. The approach relies on the extension to compressible flows of the theoretical ...
    • Modal and nonmodal stability of a stably stratified boundary layer flow 
      Article dans une revue avec comité de lecture
      PARENTE, Enza; DE PALMA, Pietro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (American Physical Society, 2020)
      The modal and nonmodal linear stability of a stably stratified Blasius boundary layer flow, composed of a velocity and a thermal boundary layer, is investigated. The temporal and spatial linear stability of such flow is ...
