    • Assessment of mixing behaviors of non-Newtonian pseudoplastic fluids in short microdevices 
      Article dans une revue avec comité de lecture
      KOUADRI, Amar; ccDOUROUM, Embarek; EL OUEDERNI, Ahmed Ridha; BENAZZA, Abdelylah; LAOUEDJ, Samir; ccKHELLADI, Sofiane (Elsevier BV, 2024-04)
      Efficient chaotic microdevices have major importance across many potential applications in industrial processes and operations, which form essential parts of microfluidic devices. In microfluidics, The Two-Layer Crossing ...
    • Numerical Investigations of Flows and Heat Transfer in Turbine Disk Cavities 
      Article dans une revue avec comité de lecture
      BEAUX, Jean-Hugues; GIRARDEAU, Julian; ccKHELLADI, Sofiane; ccDELIGANT, Michael; ccPERILHON, Christelle (ASME International (American Society of Mechanical Engineers), 2024-06)
      In gas turbines, the stator wells play a key role in the efficiency of the turbomachine. The research for performance gains requires a good understanding and an accurate modeling of the flows and heat transfers occurring ...
    • An inverse CFD actuator disk method for aerodynamic design and performance optimization of Horizontal Axis Wind Turbine blades 
      Article dans une revue avec comité de lecture
      HAMLAOUI, M.N.; ccBOUHELAL, Abdelhamid; SMAILI, Arezki; ccKHELLADI, Sofiane; ccFELLOUAH, Hachimi (Elsevier BV, 2024-07)
      In this study, advanced design technique has been introduced to determine the radial local chord distribution on the rotor blades of Horizontal Axis Wind Turbines (HAWT) based on an inverse Computational Fluid Dynamics ...
    • Linear stability of Rayleigh-Bénard-Poiseuille flow of water near 4°C in a channel bounded by slip walls 
      Article dans une revue avec comité de lecture
      BENBEGHILA, Aymen; ccOUZANI, Riadh; BENDERRADJI, Ammar; ALLOUI, Zineddine; ccKHELLADI, Sofiane (Elsevier BV, 2024-11)
      The onset of mixed convection of cold water in a horizontal channel is studied using linear stability analysis. The two walls of the channel are modeled using slip conditions and are maintained at different constant ...
    • Turbulent transition in a channel with superhydrophobic walls: anisotropic slip and shear misalignment effects 
      Article dans une revue avec comité de lecture
      ccJOUIN, Antoine; ccCHERUBINI, Stefania; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2024-02)
      Superhydrophobic surfaces dramatically reduce skin friction of overlying liquid flows. These surfaces are complex and numerical simulations usually rely on models to reduce this complexity. One of the simplest consists of ...
    • Modal and nonmodal stability analysis of turbulent stratified channel flows 
      Article dans une revue avec comité de lecture
      VARIALE, Donato; ccPARENTE, Enza; ccROBINET, Jean-Christophe; CHERUBINI, Stefania (Purpose-Led Publishing (AIP Publishing, American Physical Society - APS - and IOP Publishing), 2024-01)
      Unstable or optimally growing perturbations of turbulent flows are often representative of the energy-containing coherent structures populating the flow, as for streaks in a turbulent channel. Within this framework, this ...
    • Impinging shear layer instability in over-expanded nozzle dynamics 
      Article dans une revue avec comité de lecture
      TARSIA MORISCO, Cosimo; ccROBINET, Jean-Christophe; HERPE, Julien; SAUCEREAU, Didier (AIP Publishing, 2023-11)
      When rocket engine nozzles operate at a high degree of over-expansion, an internal flow separation occurs with a strong unsteady shock–wave boundary layer interaction. The global dynamics results in a low-frequency mode, ...
