摘要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
了增加風力發電的發電效率,本研究在葉片外形加土翼尖小翼,期能減少翼尖產生之誘導阻力,進而
提昇風力發電的輸出功率。同時考量到台灣氣候炎熱多雨,故利用多相流方法針對大雨下之風力機性
能進行數值模擬。結果發現具翼尖小翼之風力機葉片可提升推力及功率係數分別達5.7%與4.9%,且
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.
