    • Influence of pressure gradients on wall pressure beneath a turbulent boundary layer 
      Article dans une revue avec comité de lecture
      COHEN, Elie; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2018)
      This study investigates the effects of a pressure gradient on the wall pressure beneath equilibrium turbulent boundary layers. Excitation of the walls of a vehicle by turbulent boundary layers indeed constitutes a major ...
    • A Priori Tests of RANS Models for Turbulent Channel Flows of a Dense Gas 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Springer Verlag (Germany), 2018)
      Dense gas effects, encountered in many engineering applications, lead to unconventional variations of the thermodynamic and transport properties in the supersonic flow regime, which in turn are responsible for considerable ...
    • 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 ...
    • Experimental study of aerated cavitation in a horizontal venturi nozzle 
      Article dans une revue avec comité de lecture
      TOMOV, Petar; VERTENOEUIL, P.; ccRAVELET, Florent; ccSARRAF, Christophe; ccBAKIR, Farid; ccKHELLADI, Sofiane (Elsevier, 2016)
      The injection of bubbles into an already cavitating flow is a way of influencing the typical cavitating behaviour. The present article deals with experiments on aerated and non-aerated cavitation in a transparent horizontal ...
    • 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 ...
