    • Numerical study of the waste heat recovery potential of the exhaust gases from a tractor engine 
      Article dans une revue avec comité de lecture
      PUNOV, Plamen; LACOUR, Stéphanie; PÉRILHON, Christelle; PODEVIN, Pierre; DESCOMBES, Georges; EVTIMOV, Teodossi (SAGE Publications, 2015)
      The paper presents an analysis of the possibilities of exhaust gas heat recovery for a tractor engine with an output power of 110 kW. On the basis of a literature review, the Rankine cycle seems to be the most effective ...
    • 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 ...
    • Closed-loop control of wavepackets in a free shear-flow 
      Communication avec acte
      SASAKI, Kenzo; TISSOT, Gilles; CAVALIERI, André V. G.; SILVESTRE, Flávio J.; JORDAN, Peter; ccBIAU, Damien (American Institute of Aeronautics and Astronautics, 2016)
      This study aims at the attenuation of the unsteady fluctuations along a two-dimensional mixing layer which may be considered as a prototypical problem for the evaluation of es- timation and control techniques, and also a ...
    • Smoothed Particle Hydrodynamics: A consistent model for interfacial multiphase fluid flow simulations 
      Article dans une revue avec comité de lecture
      KRIMI, Abdelkader; REZOUG, Mehdi; NOGUEIRA, Xesús; RAMÍREZ, Luis; ccDELIGANT, Michael; ccKHELLADI, Sofiane (Elsevier, 2018)
      In this work, a consistent Smoothed Particle Hydrodynamics (SPH) model to deal with interfacial multiphase fluid flows simulation is proposed. A modification to the Continuum Stress Surface formulation (CSS) [1] to enhance ...
    • Experimental study on the effects of big particles physical characteristics on the hydraulic transport inside a horizontal pipe 
      Article dans une revue avec comité de lecture
      ZOUAOUI, Salah; DJEBOURI, Hassane; MOHAMMEDI, Kamal; AIT AIDER, Aomar; ccKHELLADI, Sofiane (Elsevier, 2016)
      This paper presents an experimental study of the physical characteristic effects of large particles on hydraulic transport in a horizontal pipe. The particles are spherical and are large with respect to the diameter of the ...
    • Analysis and Comparison of Transonic Buffet Phenomenon over Several Three-Dimensional Wings 
      Article dans une revue avec comité de lecture
      PALADINI, Edoardo; DANDOIS, Julien; SIPP, Denis; ccROBINET, Jean-Christophe (American Institute of Aeronautics and Astronautics, 2019)
      The transonic buffet is a complex aerodynamic instability that appears on wings and airfoils at a high subsonic Mach number and/or angle of attack. It consists of a shock oscillation that induces pressure and notably lift ...
    • 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. ...
