      MASSOUH, Fawaz; DOBREV, Ivan (2014)
      This paper is dedicated to the investigation and analysis of wind turbine wake. An experimental work is undertaken in wind tunnel on a horizontal axis wind turbine model. The velocity field in the wake is measured using ...

      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 ...

      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 ...

      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 ...

      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 ...

      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 ...

      REYT, Ida; BAILLIET, Hélène; MOREAU, Solène; VALIERE, Jean-Christophe; BALTEAN-CARLÈS, Diana; WEISMAN, Catherine; ccDARU, Virginie (Acoustical Society of America, 2013)
      Rayleigh streaming in a cylindrical acoustic standing waveguide is studied both experimentally and numerically for nonlinear Reynolds numbers from 1 to 30. Streaming velocity is measured by means of laser Doppler velocimetry ...
