    • Determination of wind turbine far wake using actuator disk 
      Communication avec acte
      AMER, Rodeyna; DOBREV, Ivan; MASSOUH, Fawaz (2014)
      The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of ...
    • Investigation of relationship between drag and lift coefficients for a generic car model 
      Communication avec acte
      DOBREV, Ivan; MASSOUH, Fawaz (BULTRANS -2014 Proceedings, 2014)
      The paper presents a study of aerodynamic characteristics of a car, which has the simplified geometric shape, so called Ahmed body. Flow around the body and the influence of its rear slant angle on drag are widely studied ...
    • Two-dimensional numerical simulations of nonlinear acoustic streaming in standing waves 
      Article dans une revue avec comité de lecture
      BALTEAN-CARLÈS, Diana; WEISMAN, Catherine; DEBESSE, Philippe; GANDIKOTA, Gurunath; ccDARU, Virginie (Elsevier, 2013)
      Numerical simulations of compressible Navier–Stokes equations in closed two-dimensional channels are performed. A plane standing wave is excited inside the channel and the associated acoustic streaming is investigated for ...
    • Experimental comparison between a counter-rotating axial-flow fan and a conventional rotor-stator stage 
      Communication avec acte
      WANG, Juan; ccRAVELET, Florent; ccBAKIR, Farid (2013)
      Based on the requirement of energy consumption level and weight and dimension restriction, compact axial machines are highly demanded in many industrial fields. The counter-rotating axial-flow fans could be a promising way ...
    • A domain decomposition matrix-free method for global linear stability 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (Elsevier, 2012)
      This work is dedicated to the presentation of a matrix-free method for global linear stability analysis in geometries composed of multi-connected rectangular subdomains. An Arnoldi technique using snapshots in subdomains ...
    • High Accuracy Volume Flow Rate Measurement Using Vortex Counting 
      Article dans une revue avec comité de lecture
      ZAARAOUI, Abdelkader; MARGNAT, Florent; ccRAVELET, Florent; ccKHELLADI, Sofiane (Elsevier, 2013)
      A prototype device for measuring the volumetric flow-rate by counting vortices has been designed and realized. It consists of a square-section pipe in which are placed a two-dimensional bluff body and a strain gauge force ...
    • Global and Koopman modes analysis of sound generation in mixing layers 
      Article dans une revue avec comité de lecture
      SONG, Ge; ALIZARD, Frédéric; ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (American Institute of Physics, 2013)
      It is now well established that linear and nonlinear instability waves play a significant role in the noise generation process for a wide variety of shear flows such as jets or mixing layers. In that context, the problem ...
