    • Space–time dynamics of optimal wavepackets for streaks in a channel entrance flow 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; CADIOU, A.; LE PENVEN, L.; DI PIERRO, B.; BUFFAT, M. (Cambridge University Press (CUP), 2018)
      The laminar–turbulent transition of a plane channel entrance flow is revisited using global linear optimization analyses and direct numerical simulations. The investigated case corresponds to uniform upstream velocity ...
    • Bifurcation analysis and frequency prediction in shear-driven cavity flow 
      Article dans une revue avec comité de lecture
      BENGANA, Y.; TUCKERMAN, L. S.; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2019)
      A comprehensive study of the two-dimensional incompressible shear-driven flow in an open square cavity is carried out. Two successive bifurcations lead to two limit cycles with different frequencies and different numbers ...
    • Global Stability Analyses Unraveling Roughness-induced Transition Mechanisms 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; LERICHE, Emmanuel; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Elsevier, 2015)
      The linear global instability and resulting transition to turbulence induced by a cylindrical roughness element of heighth and diameter d=3h immersed within an incompressible boundary layer flow along a flat plate is ...
    • Investigation on the mixture formation, combustion characteristics and performance of a Diesel engine fueled with Diesel, Biodiesel B20 and hydrogen addition 
      Article dans une revue avec comité de lecture
      ALDHAIDHAWI, Mohanad; CHIRIAC, Radu; BĂDESCU, Viorel; DESCOMBES, Georges; PODEVIN, Pierre (Elsevier, 2017)
      An experimental and numerical study was performed to investigate the impact of Biodiesel B20 (blends 20% Rapeseed methyl ester with 80 % Diesel volumetric fraction) and different energetic fractions of hydrogen content ...
    • Restricted nonlinear model for high- and low-drag events in plane channel flow 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; ccBIAU, Damien (Cambridge University Press (CUP), 2019)
      A restricted nonlinear (RNL) model, obtained by partitioning the state variables into streamwise-averaged quantities and superimposed perturbations, is used in order to track the exact coherent state in plane channel flow ...
    • On the design of propeller hydrokinetic turbines: the effect of the number of blades 
      Article dans une revue avec comité de lecture
      BRASIL JUNIOR, Antonio Cesar Pinho; MENDES, Rafael C. F.; WIRRIG, Théo; NOGUERA, Ricardo; OLIVEIRA, Felamingo De Taygoara (Springer Verlag, 2019)
      A design study of propeller hydrokinetic turbines is explored in the present paper, where the optimized blade geometry is determined by the classical Glauert theory applicable to the design of axial flow turbines (hydrokinetic ...
    • Comparison of various hemodynamic models for applications to cfd in stented arteries 
      Article dans une revue avec comité de lecture
      CHABI, Fatiha; NOGUERA, Ricardo; MAUREL, Blandine; ccCHAMPMARTIN, Stephane; ccSARRAF, Christophe (icmmb19.org, 2014)
      A design study of propeller hydrokinetic turbines is explored in the present paper, where the optimized blade geometry is determined by the classical Glauert theory applicable to the design of axial flow turbines (hydrokinetic ...
