  1. 1. On Turbulent Wall Jets

    Författare :Hans Abrahamsson; Chalmers University of Technology; []
    Nyckelord :self-preservation; similarity theory; scaling laws; local flow reversals; high turbulence levels; turbulent kinetic energy budget; two-dimensional; turbulent; hot-wire anemometry; wall jet; three-dimensional; pulsed hot-wire anemometry;

    Sammanfattning : An experimental investigation of the two- and three-dimensional turbulent wall jets has been conducted. The measurements have been performed using different hot-wire techniques in large scale wall jet facilities, and the measurements were focused on the fully-developed region of the flow. LÄS MER

  2. 2. Wakes behind wind turbines - Studies on tip vortex evolution and stability

    Författare :Ylva Odemark; Jens Fransson; Jens Madsen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power; aerodynamics; hot-wire anemometry; vortex dynamics;

    Sammanfattning : The increased fatigue loads and decreased power output of a wind turbine placed in the wake of another turbine is a well-known problem when building new wind power farms. In order to better estimate the total power output of a wind power farm, knowledge about the development and stability of wind turbine wakes is crucial. LÄS MER
