Küçük Kapasiteli, Yatay Eksenli ve Akış Hızlandırıcılı Rüzgar Türbinlerinin Performans Analizi

Kentsel ve kırsal alanlarda, konutların ve küçük işletmelerin kullanımına yönelik yenilenebilir enerji teknolojilerinden faydalanılarak elektrik enerjisi üretilmesi ülkelerin enerji ekonomisi ve stratejisi açısından oldukça önemlidir. Bu çalışmada, düşük rüzgâr hızlarında verimli çalışabilen, kentsel ve kırsal alanlarda konutların kullanımına yönelik küçük kapasiteli, yatay eksenli ve akış hızlandırıcılı (yayıcı) rüzgâr türbinlerinin tasarımı için analitik çözümleme ve modelleme yapılmıştır. Bunun için önce rotor çapı 1 m olan küçük bir rüzgar türbini seçilmiş, daha sonra bu rüzgar türbini akış hızlandırıcılı olarak modellenerek performans değerleri karşılaştırılmıştır. Elde edilen sonuçlara ve seçilen aerodinamik karakteristiklere göre, serbest akış rüzgar hızı 10 m/s iken açık akıştaki rüzgar türbini üzerinden elde edilen güç değeri 246,17 W iken, akış hızlandırıcılı rüzgar türbini üzerinde elde edilen güç değeri 333,2 W olarak hesaplanmıştır.

Performance Analysis of Small Capacity, Horizontal Axis and Flow Accelerator Wind Turbines

Generating electricity by using renewable energy technologies for the use of residences and small businesses in urban and rural areas is very important for the energy economy and strategy of countries. In this study, analytical analysis and modeling were carried out for the design of small capacity, horizontal axis and flow accelerator (diffuser) wind turbines that can operate efficiently at low wind speeds and are intended for residential use in urban and rural areas. For this, first a small wind turbine with a rotor diameter of 1 m was selected, then this wind turbine was modeled with a flow accelerator and its performance values were compared. According to the results and the selected aerodynamic characteristics, the free flow wind speed was 10 m/s and the power value obtained over the open flow wind turbine was 246,17 W, while the power value obtained on the flow accelerator wind turbine was calculated as 333,2 W.
