    • Constrained sparse Galerkin regression 
      Article dans une revue avec comité de lecture
      BRUNTON, Steven L.; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2018)
      The sparse identification of nonlinear dynamics (SINDy) is a recently proposed data-driven modelling framework that uses sparse regression techniques to identify nonlinear low-order models. With the goal of low-order models ...
    • Aeroacoustic Study of the Interaction of a Rotating Blade with a Batchelor Vortex 
      Article dans une revue avec comité de lecture
      ZEHNER, Paul; FALISSARD, Fabrice; ccGLOERFELT, Xavier (American Institute of Aeronautics and Astronautics, 2018)
      The aeroacoustic response of the orthogonal interaction of a rotating blade with an isolated Batchelor vortex is studied by means of numerical simulation. The relative influence of the vortex tangential and axial velocity ...
    • An unexpected balance between outer Rayleigh streaming sources 
      Article dans une revue avec comité de lecture
      BALTEAN-CARLÈS, Diana; WEISMAN, Catherine; TABAKOVA, S.; BAILLIET, Hélène; ccDARU, Virginie (Cambridge University Press (CUP), 2019)
      Acoustic streaming generated by a plane standing wave between two infinite plates or inside a cylindrical tube is considered, under the isentropic flow assumption. A two-dimensional analysis is performed in the linear case ...
    • Large scale dynamics of a high Reynolds number axisymmetric separating/reattaching flow 
      Article dans une revue avec comité de lecture
      PAIN, R; WEISS, P-E; DECK, S; ccROBINET, Jean-Christophe (American Institute of Physics, 2019)
      A numerical study is conducted to unveil the large scale dynamics of a high Reynolds number axisymmetric separating/reattaching flow at M∞ = 0.7. The numerical simulation allows us to acquire a high rate sampled unsteady ...
    • Laminar–turbulent transition in channel flow with superhydrophobic surfaces modelled as a partial slip wall 
      Article dans une revue avec comité de lecture
      PICELLA, Francesco; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2019)
      Superhydrophobic surfaces are capable of trapping gas pockets within the micro-roughnesses on their surfaces when submerged in a liquid, with the overall effect of lubricating the flow on top of them. These bio-inspired ...
    • 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. ...
    • Various approaches to determine active regions in an unstable global mode: application to transonic buffet 
      Article dans une revue avec comité de lecture
      PALADINI, Edoardo; MARQUET, Olivier; SIPP, Denis; DANDOIS, Julien; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2019)
      The transonic flow field around a supercritical airfoil is investigated. The objective of the present paper is to enhance the understanding of the physical mechanics behind two-dimensional transonic buffet. The paper is ...
