    • 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 ...
    • Transonic buffet instability: From two-dimensional airfoils to three-dimensional swept wings 
      Article dans une revue avec comité de lecture
      PALADINI, Edoardo; BENEDDINE, Samir; DANDOIS, Julien; SIPP, Denis; ccROBINET, Jean-Christophe (American Physical Society, 2019)
      The objective of the present study is to explain the evolution of the transonic buffet phenomenon from two-dimensional airfoils to three-dimensional swept wings by a global stability analysis. With respect to two-dimensional ...
    • Nonlinear optimal large-scale structures in turbulent channel flow 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (Elsevier, 2018)
      Coherent structures in turbulent shear flows take the form of packets of hairpin vortices reaching the outer region of the boundary layer along with streaks of different size, going from the near-wall to the outer region. ...
    • Computing heteroclinic orbits using adjoint-based methods 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; SCHNEIDER, T. M.; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2018)
      Transitional turbulence in shear flows is supported by a network of unstable exact invariant solutions of the Navier–Stokes equations. The network is interconnected by heteroclinic connections along which the turbulent ...
    • Instabilities in non-ideal fluids 
      Article dans une revue avec comité de lecture
      ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2019)
      The recent study of Ren et al. (J. Fluid Mech., vol. 871, 2019, pp. 831–864) investigated the hydrodynamic linear stability of a compressible boundary layer over an insulated flat plate for a non-ideal gas (supercritical ...
    • A sharp immersed boundary method based on penalization and its application to moving boundaries and turbulent rotating flows 
      Article dans une revue avec comité de lecture
      SPECKLIN, Mathieu; DELAURÉ, Y. (Elsevier, 2018)
      This paper presents an Immersed Boundary Method (IBM) for handling flows in the presence of fixed and moving solids with complex geometries. The method is based on a penalization approach and designed to preserve the ...
    • Impact of Biodiesel Blends and Di-Ethyl-Ether on the Cold Starting Performance of a Compression Ignition Engine 
      Article dans une revue avec comité de lecture
      CLENCI, Adrian; NICULESCU, Rodica; DANLOS, Amélie; IORGA-SIMĂN, Victor; TRICĂ, Alina (MDPI, 2016)
      The use of biodiesel fuel in compression ignition engines has the potential to reduce CO2, which can lead to a reduction in global warming and environmental hazards. Biodiesel is an attractive fuel, as it is made from ...
