    • A numerical study of the coupling between Rayleigh streaming and heat transfer at high acoustic level 
      Article dans une revue avec comité de lecture
      WEISMAN, Catherine; BALTEAN-CARLÈS, Diana; BAILLIET, Hélène; ccDARU, Virginie (Acoustical Society of America (ASA), 2021)
      coupling between thermal effects and Rayleigh streaming in a standing wave guide at high acoustic levels is analyzed numerically. The approach is guided by the recent analytical study, showing that reverse streaming cells ...
    • Acoustically induced thermal effects on Rayleigh streaming 
      Article dans une revue avec comité de lecture
      WEISMAN, Catherine; BALTEAN-CARLÈS, Diana; BAILLIET, Hélène; ccDARU, Virginie (Cambridge University Press (CUP), 2021)
      The present study focuses on acoustically induced thermal effects on Rayleigh streaming inside a resonator. Firstly, we consider the effect of the transverse (or wall-normal) mean temperature gradient on the acoustic ...
    • Texture shape effects on hydrodynamic journal bearing performances using mass-conserving numerical approach 
      Article dans une revue avec comité de lecture
      MANSER, Belkacem; BELAIDI, Idir; HAMRANI, Abderrachid; ccBAKIR, Farid; ccKHELLADI, Sofiane (2019)
      lt is a known fact that incorporating textures in the contact surfaces can significantly enhance bearing performances. The purpose of this paper is to outline the effects of texture bottom profiles and contour geometries ...
    • Linear and nonlinear optimal growth mechanisms for generating turbulent bands 
      Article dans une revue avec comité de lecture
      PARENTE, ENZA; DE PALMA, Pietro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (Cambridge University Press, 2022)
      Recently, many authors have investigated the origin and growth of turbulent bands in shear flows, highlighting the role of streaks and their inflectional instability in the process of band generation and sustainment. ...
    • 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 ...
    • 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 ...
    • 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 ...
