    Abstract: 本研究分為兩個部分,第一部分以垂直軸風力發電機轉子採用H升力型及Savonius阻力型,探討其在風扇流中的性能特性,並與其在自由流的性能特性比較,實驗結果顯示垂直軸風力發電機在風扇流中並沒有較佳的功率輸出性能。
    The thesis studies of waste wind energy recovery of exhaust fans by wind turbines, which is divided into two parts.The first part of thesis studies investigates the aerodynamic characteristics of vertical-axis wind turbine (VAWT) with H rotor and Savonius rotor in fan flow. Results show that the vertical-axis wind turbine does not had better power output in fan flow
    The second part of thesis studies compare with wind tunnel test and experimentally investigates the aerodynamic characteristics of horizontal-axis wind turbine (HAWT) with different parameters such as: the pitch angle, rotor diameter, the distances between fan and rotor, three kinds of fans. Results show the pitch angle of the blades is fixed at 7.5°, rotor diameter of 60 cm, the distances between fan and rotor of 5 cm and one fan is the best combination.It’s power output above 260% free stream.Finally, observe the fan outlet flow field by laser Doppler velocimetry.Section L/Dh=0.111 has local high speed and the section L/Dh=0.444 have uniform flow field.Single fan measured distance increases with minimal impact.The aerodynamic characteristics of wind turbine dominated by local high speed, so the wind turbine can not get a higher power output by four and nine fan.
