    • Modal and non-modal linear stability of Poiseuille flow through a channel with a porous substrate 
      Article dans une revue avec comité de lecture
      GHOSH, Souvik; BREUGEM, Wim-Paul; BRANDT, Luca; ccLOISEAU, Jean-Christophe (Elsevier, 2019)
      We present modal and non-modal linear stability analyses of Poiseuille flow through a plane channel with a porous substrate modeled using the Volume Averaged Navier–Stokes (VANS) equations. Modal stability analysis shows ...
    • Study of Bonding Formation between the Filaments of PLA in FFF Process 
      Article dans une revue avec comité de lecture
      KALLEL, Achraf; ccKOUTIRI, Imade; BABAEITORKAMANI, E.; KHAVANDI, A.; TAMIZIFAR, M.; SHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas (2019)
      Fused filament fabrication (FFF) is an additive manufacturing (AM) process that provides physical objects commonly used for modeling, prototyping and production applications. The major drawback of this process is poor ...
    • 1/f noise and long-term memory of coherent structures in a turbulent shear flow 
      Article dans une revue avec comité de lecture
      GISSINGER, C.; FAUVE, S.; ccPEREIRA, Michaël (American Physical Society (APS), 2019)
      A shear flow of liquid metal (Galinstan) is driven in an annular channel by counter-rotating traveling magnetic fields imposed at the endcaps. When the traveling velocities are large, the flow is turbulent and its azimuthal ...
    • A Thin Film Fluid Structure Interaction Model for the Study of Flexible Structure Dynamics in Centrifugal Pumps 
      Article dans une revue avec comité de lecture
      ALBADAWI, Abdulaleem; SPECKLIN, Mathieu; CONNOLLY, Robert; DELAURÉ, Yan (American Society of Mechanical Engineers, 2018)
      This paper describes a fluid-structure interaction (FSI) model for the study of flexible cloth-like structures or the so-called rags in flows through centrifugal pumps. The structural model and its coupling to the flow ...
    • Small wind turbine augmentation: Experimental investigations of shrouded- and twin-rotor wind turbine systems 
      Article dans une revue avec comité de lecture
      LIPIAN, Michal; DOBREV, Ivan; KARCZEWSKI, Maciej; MASSOUH, Fawaz; JOZWIK, Krzysztof (Elsevier, 2019)
      An increase in the efficiency of Small Wind Turbines (SWTs) by aerodynamic optimisation of the blade geometry is limited (low Reynolds number influence). Solutions such as the Diffuser-Augmented Wind Turbine (DAWT) and the ...
    • Intermittency and transition to chaos in the cubical lid-driven cavity flow 
      Article dans une revue avec comité de lecture
      LERICHE, Emmanuel; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (IOP Publishing, 2016)
      Transition from steady state to intermittent chaos in the cubical lid-driven flow is investigated numerically. Fully three-dimensional stability analyses have revealed that the flow experiences an Andronov-Poincaré-Hopf ...
    • Roughness-induced transition by quasi-resonance of a varicose global mode 
      Article dans une revue avec comité de lecture
      BUCCI, Michele Alessandro; PUCKERT, Dominik K.; ANDRIANO, Cesare; CHERUBINI, Stefania; RIST, Ulrich; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2017)
      The onset of unsteadiness in a boundary-layer flow past a cylindrical roughness element is investigated for three flow configurations at subcritical Reynolds numbers, both experimentally and numerically. On the one hand, ...
