    • Sensitivity analysis of optimal transient growth for turbulent boundary layers 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; FILLIARD, Guillaume; ccROBINET, Jean-Christophe (Elsevier, 2015)
      Structural approaches based on modal decomposition of the flow dynamics have gained acceptance for a wide variety of turbulent shear flows. In this context, a singular value decomposition associated with a governing operator, ...
    • Development of a third-order accurate vorticity confinement scheme 
      Article dans une revue avec comité de lecture
      COSTES, M.; PETROPOULOS, I.; ccCINNELLA, Paola (ELSEVIER, 2016)
      A new 3rd-order Vorticity Confinement scheme is presented as an extension of the original VC2 scheme developed by Steinhofffor the resolution of the fluid dynamic equations. The theoretical developments are explained, and ...
    • Investigation of high-order methods in large-eddy simulation of separated flow in a channel with periodic constrictions 
      Chapitre d'ouvrage scientifique
      CINNELLA, Paola; ccGLOERFELT, Xavier (Springer, 2018)
      In large-eddy simulations (LES), only the dynamics of large scales is computed and the effect of smaller scales is modelled. Scale separation is however difficult to establish since the low-pass filtering arises from a ...
    • 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 ...
