| Summary: | 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 wind turbines arranged in regular arrangement of 3 rows and 3 columns. Wind turbine arrays distances are S=1.76H and S=2.64H, where H is wind turbine hub center height from the ground.
Wind speed measurements showed that heights between Z/H=0.4~0.6, due to fan blade rotation, wind speeds change between before and after. In heights above Z/H=1.2 wind speeds vary insignificantly.
Regardless of the distance between the wind turbine arrays of 1.76H or 2.64H, the wake flows of the second and third row of wind turbines exhibit the characteristic of wake flow similarity.
After the wind through wind turbine, wind turbine blades and energy conversion, makes windmill rear wind speeds decreased significantly. But away from the wind, turbine wind speed profiles gradually restore. When the distance between each row of wind turbines increased from 1.76H to 2.64H, the wind speed profiles restore significantly .
