    • Numerical investigation of three-dimensional partial cavitation in a Venturi geometry 
      Article dans une revue avec comité de lecture
      GOUIN, Camille; JUNQUEIRA-JUNIOR, Carlos; GONCALVES DA SILVA, Eric; ccROBINET, Jean-Christophe (AIP Publishing, 2021)
      Sheet cavitation appears in many hydraulic applications and can lead to technical issues. Some fundamental outcomes, such as, the complex topology of 3-dimensional cavitation pockets and their associated dynamics need to ...
    • Global transition dynamics of flow in a lid-driven cubical cavity 
      Article dans une revue avec comité de lecture
      RANJAN, Rajesh; UNNIKRISHNAN, Sasidharan; GAITONDE, Datta; ccROBINET, Jean-Christophe (Springer Science and Business Media LLC, 2021)
      The dynamics of a fully three-dimensional lid-driven cubical cavity (3D-LDC) flow at several postcritical conditions, i.e., beyond the first bifurcation, are elucidated using both linear and nonlinear analyses. When the ...
    • Influence of freestream turbulence on the flow over a wall roughness 
      Article dans une revue avec comité de lecture
      BUCCI, Michele Alessandro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (American Physical Society (APS), 2021)
      The effect of freestream turbulence on the dynamics of an incompressible flow past a cylindrical roughness element in subcritical conditions (i.e., for Reynolds numbers below the onset of linear instability) has been ...
    • An unexpected balance between outer Rayleigh streaming sources 
      Article dans une revue avec comité de lecture
      BALTEAN-CARLÈS, Diana; WEISMAN, Catherine; TABAKOVA, S.; BAILLIET, Hélène; ccDARU, Virginie (Cambridge University Press (CUP), 2019)
      Acoustic streaming generated by a plane standing wave between two infinite plates or inside a cylindrical tube is considered, under the isentropic flow assumption. A two-dimensional analysis is performed in the linear case ...
    • 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 ...
    • 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 ...
    • Influence of the Shape on the Roughness-Induced Transition 
      Ouvrage scientifique
      CHERUBINI, Stefania; LERICHE, Emmanuel; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Springer, 2015)
      lobal instability analysis of the three-dimensional flow past two rough- ness elements of different shape, namely a cylinder and a bump, is presented. In both cases, the eigenspectrum is made of modes characterised by a ...
