Abstract

Aerodynamics mechanisms on a solar panel were studied using Computational Fluid Dynamics methodology at different wind directions. The wind velocity was chosen as 10 m/s that corresponding turbulent flow. The inclination angle of the panel was fixed as 25°, while the wind directions were varied as 180°, 135°, 45°, and 0°. Governing equations were solved by utilizing a finite volume method with a realizable k-ε turbulence model and standard wall functions. The results showed that the recirculation area occurred for the straight wind directions, but it was not observed for the oblique wind directions. The highest pressure coefficients occurred at the leading edges of the solar panel and they reduced to the trailing edge for all wind directions. The maximum drag and uplift coefficient was obtained at the wind direction of 0° and 180°, respectively.

Abstract

Bir güneş panelindeki aerodinamik mekanizmalar, farklı rüzgar yönlerinde Hesaplamalı Akışkanlar Dinamiği kullanılarak incelenmiştir. Rüzgar hızı, türbülanslı akışa karşılık gelen 10m/ s olarak seçilmiştir. Panelin eğim açısı 25° olarak sabitlenirken, rüzgar yönleri 180°, 135°, 45° ve 0 ° olarak değiştirilmiştir. Korunum denklemleri, realizable k-ε türbülans modeli ve standart duvar fonksiyonları ile sonlu hacim yöntemi kullanılarak çözülmüştür. Sonuçlar, yeniden dolaşım bölgesinin düz rüzgar yönlerinde meydana geldiğini, ancak eğik rüzgar yönleri için gözlemlenmediğini göstermiştir. En yüksek basınç katsayıları panelin ön kenarlarında meydana gelmiş ve daha sonra tüm rüzgar yönleri için arka kenara doğru azalmıştır. 0° ve 180° rüzgar yönleri, maksimum sürükleme ve kaldırma açısından sırasıyla kritik bulunmuştur.
