碩士 === 國立臺灣海洋大學 === 河海工程學系 === 102 === This study used pitot tube and the smoke flow visualization techniques to measure and observe the wind flow characteristics of eight wind turbines with staggered arrangement of three rows by three columns. The distance, S between wind turbines are S=1.76H and S=2.64H; where H is the wind turbine hub center height from the ground.
Measurement results show that between heights Z/H=1.4 and Z/H=0.4, wind speeds change significantly in the front and rear the wind turbine due to the influence of blade rotating. The wind speed profiles in the front the first and the second rows of wind turbine are fond quite close.

As the space of wind turbine S increased from 1.76H to 2.64H, the wind speed in the front of third row of wind turbines increased. This enhance the power generation for the third row wind turbines.
The measured wind speed profiles behind the wind turbines exhibited the wake flow similarity characteristics.
