Abstract:	本研究將重建一包含輪穀三維的NREL VI型兩葉片式風力渦輪機之數值模型，並與NASA AMES風洞的實驗測試數據作比較。三維葉片的流場將在非慣性的旋轉座標上作Navier-Stokes方程式之數值解析。本文數值方法將採用不可壓縮流的高解析算則，並配合Spallart-Allmras單方程紊流模式，藉以探討氣動力現象與相關之壓力係數、推力和流場的速度分佈。再者，本文並與二維的S809機翼氣動力數據作相關之數值比對。 This work will reconstruct a three-dimensional 2-blade wind turbine of hub as NREL VI type model and compared to test data in NASA AMES Wind Tunnel. The three-dimensional wind blade flowfields will be simulated on non-inertial rotational main frame by Na
