    • Assessment of a high-order shock-capturing central-difference scheme for hypersonic turbulent flow simulations 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (Elsevier, 2021-11)
      High-speed turbulent flows are encountered in most space-related applications (including exploration, tourism and defense fields) and represent a subject of growing interest in the last decades. A major challenge in ...
    • Finite-rate chemistry effects in turbulent hypersonic boundary layers: A direct numerical simulation study 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (American Physical Society, 2021-05)
      The influence of high-enthalpy effects on hypersonic turbulent boundary layers is investigated by means of direct numerical simulations (DNS). A quasiadiabatic flat-plate air flow at free-stream Mach number equal to 10 is ...
    • Numerical Investigation of High‑Speed Turbulent Boundary Layers of Dense Gases 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINNELLA, Paola; GRASSO, Francesco; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Springer, 2020-03)
      High-speed turbulent boundary layers of a dense gas (PP11) and a perfect gas (air) over flat plates are investigated by means of direct numerical simulations and large eddy simulations. The thermodynamic conditions of the ...
    • 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. ...
    • 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 ...
