    • 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 ...
    • A high-order density-based finite volume method for the computation of all-speed flows 
      Article dans une revue avec comité de lecture
      NOGUEIRA, Xesús; RAMÍREZ, Luis; CHASSAING, Jean-Camille; COLOMINAS, Ignasi; ccKHELLADI, Sofiane (Elsevier, 2016)
      In this paper we present a high-order density-based finite-volume framework for all-speed flows. The formulation is based on high-order variable reconstructions performed using Moving Least Squares approximations. In ...
    • 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 ...
    • New high-resolution-preserving sliding mesh techniques for higher-order finite volume schemes 
      Article dans une revue avec comité de lecture
      RAMÍREZ, Luis; FOULQUIÉ, Charles; NOGUEIRA, Xesús; CHASSAING, Jean-Camille; COLOMINAS, Ignasi; ccKHELLADI, Sofiane (Elsevier, 2015)
      This paper presents a new sliding mesh technique for the computation of unsteady viscous flows in the presence of rotating bodies. The compressible Euler and incompressible Navier–Stokes equations are solved using a ...
    • Roughness-induced transition by quasi-resonance of a varicose global mode 
      Article dans une revue avec comité de lecture
      BUCCI, Michele Alessandro; PUCKERT, Dominik K.; ANDRIANO, Cesare; CHERUBINI, Stefania; RIST, Ulrich; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2017)
      The onset of unsteadiness in a boundary-layer flow past a cylindrical roughness element is investigated for three flow configurations at subcritical Reynolds numbers, both experimentally and numerically. On the one hand, ...
    • Intermittency and transition to chaos in the cubical lid-driven cavity flow 
      Article dans une revue avec comité de lecture
      LERICHE, Emmanuel; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (IOP Publishing, 2016)
      Transition from steady state to intermittent chaos in the cubical lid-driven flow is investigated numerically. Fully three-dimensional stability analyses have revealed that the flow experiences an Andronov-Poincaré-Hopf ...
