| Popis: | The objective of this study was to place a model wind turbine into a wind tunnel and measure the wind characteristics in the vicinity of the spinning rotor for a variety of flow conditions. A 0.53 meter diameter model wind turbine was placed in the Meteorological Wind Tunnel facility at Colorado State University. Four different approach flow conditions were studied. These were two different mean wind speeds (6 and 7.6 m/s) and two different turbulence conditions (0.1% and 1.5% intensity). For each of these test conditions the three-dimensional wind field was measured between 3 rotor diameters upwind to 1 2 rotor diameter downwind. The rotor power coefficient versus tip speed ratio was also obtained. |
