    • 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 ...
    • 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 ...
    • Optimal perturbation for two-dimensional vortex systems: route to non-axisymmetric state 
      Article dans une revue avec comité de lecture
      NAVROSE; JOHNSON, Author H. G.; BRION, Véronique; JACQUIN, Laurent; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2018)
      We investigate perturbations that maximize the gain of disturbance energy in a two-dimensional isolated vortex and a counter-rotating vortex pair. The optimization is carried out using the method of Lagrange multipliers. ...
    • Dense-gas effects on compressible boundary-layer stability 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; GRASSO, Francesco; ccROBINET, Jean-Christophe; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2020)
      A study of dense-gas effects on the stability of compressible boundary-layer flows is conducted. From the laminar similarity solution, the temperature variations are small due to the high specific heat of dense gases, ...
