Abstract

Rüzgar türbinlerinde kanat profili seçimi türbinin aerodinamik performansı açısından çok önemlidir. Bu çalışmada dikey eksenli H-Darrieus rüzgar türbinlerinde simetrik ve asimetrik kanat profili kullanımının türbin verimine olan etkisi sayısal olarak incelenmiştir. Beş simetrik kanat profili (NACA0009, NACA0012, NACA0015, NACA0018, NACA0021) ile beş asimetrik kanat profilinin (NACA2412, NACA4412, NACA6412, NACA8412, NACA10412) H-Darrieus rüzgar türbininde kullanılması durumunda türbin verimi incelenmiştir. Hesaplamalarda Çift Çoklu Akım Tüpü (ÇÇAT) (Double Multiple Stream Tube-DMST) yöntemi kullanılmıştır. NACA0018 kanat profili kullanılan türbinde en yüksek güç katsayısı CPmax=0.4791 bulunurken, NACA2412 kanat profili kullanılan türbinde en yüksek güç katsayısı ise CPmax=0.4726 bulunmuştur. NACA0018 ve NACA2412 kanat profilleri için kanat uç hız oranının () güç katsayısına (CP) ve rotor açısının ( moment değerlerine () göre değişimlerini veren matematiksel bağıntılar elde edilmiştir. Elde edilen bağıntıların hepsinde regresyon katsayısı oldukça yüksektir (r^2>0.99).

Comparison of symmetrical and asymmetrical airfoil usage on H-Darrieus Wind Turbine

Abstract

Airfoil choice is vital for wind turbines. In this study effects of symmetrical and asymmetrical airfoil types on vertical axis H-Darrieus turbine performance are investigated. Coefficient of performance (CP) of H-Darrieus türbine is investigated for five symmetric (NACA0009, NACA0012, NACA0015, NACA0018, NACA0021) and five asymmetric airfoils (NACA2412, NACA4412, NACA6412, NACA8412, NACA10412). In the calculations Double Multiple Stream Tube (DMST) model is used. For NACA0018 airfoil maximum power coefficient is found as CPmax=0.4791 whereas maximum power coefficient for NACA2412 airfoil is found as CPmax=0.4726. Mathematical relations for coefficient of performance (CP) respect to tip speed ratio () and torque () respect to azimuth angle (are derived. Regression cofficients of the relations are found very high (r^2>0.99).
