Abstract

Airfoils are widely used in fluid flow applications such as aircraft, vehicles, and particularly in the blades of wind turbines, where aerodynamic efficiency plays a key role in enhancing performance and supporting sustainability. In this study, experimental investigations were carried out on two airfoil profiles commonly used in Darieus type vertical axis wind turbine applications: NACA 0015 and NACA 2415. The experiments are performed in two main parts: aerodynamic force measurements and surface oil flow visualization. In the first part, the aerodynamic performance of both airfoils is analyzed under two main configurations: the baseline model without guide vanes, and modified setups incorporating guide vanes with arc lengths increasing in 10° increments, up to a maximum of 50°. The effects of guide vane integration on the lift and drag characteristics are evaluated and compared. Graphs showing the variation of lift coefficient (CL) and drag coefficient (CD) with angle of attack (AoA) are provided for each case and for multiple freestream velocities. These results aim to highlight the influence of guide vane implementation on aerodynamic force generation and overall performance enhancement.

Özet

Kanat profilleri, uçaklar, araçlar ve özellikle rüzgar türbinlerinin kanatlarında olmak üzere akışkan akışının söz konusu olduğu uygulamalarda yaygın olarak kullanılmaktadır. Bu yapılarda aerodinamik verimlilik, performansı artırmak ve sürdürülebilirliği desteklemek açısından önemli bir rol oynamaktadır. Bu çalışmada, Darieus tipi dikey eksenli rüzgar türbini uygulamalarında yaygın olarak kullanılan iki kanat profili olan NACA 0015 ve NACA 2415 üzerinde deneysel araştırmalar gerçekleştirilmiştir. Deneyler iki ana bölümde yürütülmüştür: aerodinamik kuvvet ölçümleri ve yüzey yağ akışı görselleştirmesi. İlk bölümde, her iki kanat profilinin aerodinamik performansı, yönlendirici kanat içermeyen temel model ve 10°’lik açı aralıkları ile 50°’ye kadar çıkan yay uzunluklarında yönlendirici kanatların entegre edildiği modifiye konfigürasyonlar altında analiz edilmiştir. Yönlendirici kanat entegrasyonunun kaldırma ve sürükleme karakteristikleri üzerindeki etkileri değerlendirilmiş ve karşılaştırılmıştır. Her bir durum ve farklı serbest akış hızları için kaldırma katsayısı ve sürükleme katsayısı ile hücum açısı arasındaki değişimi gösteren grafikler sunulmuştur. Bu sonuçlar, yönlendirici kanat uygulamasının aerodinamik kuvvet üretimi ve genel performans artışı üzerindeki etkisini ortaya koymayı amaçlamaktadır.
