摘 要:
将目前广泛使用的风力机桨叶翼型FFAW3-211进行了“涡轮化”修改,显著增加了其弯度;并在小型低速风洞中对风力机模型进行了一系列对比吹风实验,风速范围8～15 m/s,安装角6°～14°;实验结果表明,安装改型翼型的桨叶后,在各种条件下风力机的风能利用系数均大大提高.[著者文摘]

Abstract:
The widely used airfoil FFA-W3-211 was modified toward the ＂turbine-like＂ airfoil so that the camber of its pressure surface was increased. Then a number of comparative experiments of the wind turbines with prototype and modified airfoils were conducted in a small low-speed tunnel, with the wind speed ranges of 8-15m/s, the pitch angles of 6°-14°. The experimental results show that the power coefficients of the wind turbine with bigger cambered airfoils are enhanced significantly at various operating conditions.[著者文摘]
Key words:
horizontal-axis wind turbine; power enhancement; FFA-W3-211; airfoil camber
