    Abstract: 有鑑於地球環境日益惡化,科學家開始研究較環保的替代能源,風力發電因而蓬勃發展。本文首先以
    S809機翼剖面及NREL Phase VI 風力機葉片為原型進行數值模擬驗證',和實驗比對獲得良好結果。為
    大雨亦可增加風力機葉片推力之1.6% '本研究結果可應用在未來風力機葉片設計上。
    As global wanning becomes more severe and wind turbine continues to grow larger, problems with turbine
    blade aerodynamics is also become more critical. In recent years, the benefit of the airplane winglet leads us
    to put this device on wind turbine blades to improve the efficiency of power generating. In this study first the
    2D S809 airfoil and 3D NREL Phase VI wind turbine blade simulation are validated. Then the heavy rain
    effect is simulated through the two--phase flow numerical method and the performance of wingleted turbine
    with-without-rain conditions is fully investigated. Our results show that about 5.7% and 4.9% performance
    increase in thrust and power respectively are achieved if winglet is added to our turbine blade; and heavy
    rain situation will also enhance the thrust of this wind turbine by about 1.6 percent. Thus these findings
    should be considered in future wind turbine design phase.
