    • Investigation of the flow dynamics in a channel constricted by periodic hills 
      Communication avec acte
      CINNELLA, Paola; ccGLOERFELT, Xavier (American Institute of Aeronautics and Astronautics, 2015)
      The present study aims at getting better insight of the complex flow dynamics in a channel constricted by periodic hills. This is a popular test case ofer used to assess LES and RANS/LES models, which appears as a compendium ...
    • Dense gas effects in inviscid homogeneous isotropic turbulence 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; CONTENT, C.; GRASSO, Francesco; ccSCIACOVELLI, Luca (Cambridge University Press (CUP), 2016)
      A detailed numerical study of the influence of dense gas effects on the large-scale dynamics of decaying homogeneous isotropic turbulence is carried out by using the van der Waals gas model. More specifically, we focus on ...
    • Inertial effects on acoustic Rayleigh streaming flow: Transient and established regimes 
      Article dans une revue avec comité de lecture
      WEISMAN, Catherine; BALTEAN-CARLÈS, Diana; REYT, Ida; BAILLIET, Hélène; ccDARU, Virginie (Elsevier, 2017)
      The effect of inertia on Rayleigh streaming generated inside a cylindrical resonator where a mono-frequency standing wave is imposed, is investigated numerically and experimentally. To this effect, time evolutions of ...
    • On wall pressure fluctuations and their coupling with vortex dynamicsin a separate d–reattache d turbulent flow over a blunt flat plate 
      Article dans une revue avec comité de lecture
      TENAUD, C; PODVIN, B; FRAIGNEAU, Y; ccDARU, Virginie (Elsevier, 2016)
      This study deals with the numerical predictions through Large-Eddy Simulation ( LES ) of the separated–reattached turbulent flow over a blunt flat plate for analyzing main coherent structure features and theirrelation to ...
    • Strong scaling of numerical solver for supersonic jet flow configurations 
      Article dans une revue avec comité de lecture
      JUNQUEIRA-JUNIOR, Carlos; AZEVEDO, João Luiz F.; PANETTA, Jairo; WOLF, William R.; YAMOUNI, Sami (Springer Verlag, 2019)
      Acoustics loads are rocket design constraints which push researches and engineers to invest efforts in the aeroacoustics phenomena which is present on launch vehicles. Therefore, an in-house computational fluid dynamics ...
    • Acoustic and streaming velocity components in a resonant waveguide at high acoustic levels 
      Article dans une revue avec comité de lecture
      REYT, Ida; BAILLIET, Hélène; WEISMAN, Catherine; BALTEAN-CARLÈS, Diana; ccDARU, Virginie (Acoustical Society of America, 2017)
      Rayleigh streaming is a steady flow generated by the interaction between an acoustic wave and a solid wall, generally assumed to be second order in a Mach number expansion. Acoustic streaming is well known in the case of ...
    • Conventional rotational molding process and aerodynamic characteristics of an axial-flow hollow blades rotor 
      Article dans une revue avec comité de lecture
      LUCAS, Albert; DANLOS, Amélie; ccSHIRINBAYAN, Mohammadali; MOTAHARINEJAD, Vajihe; PARIDAENS, Richard; ccBENFRIHA, Khaled; ccTCHARKHTCHI, Abbas; ccBAKIR, Farid (Springer Verlag, 2019)
      n this work, the rotational molding process is developed to manufacture in one piece an axial-flow turbomachine rotor with hollow blades. Giving to our knowledge, this process has never been employed in the making of these ...
