Within the framework of blade aerodynamic design, the maximum aerodynamic efficiency, power production, and minimum thrust force are the targets to obtain. This paper describes an improved optimization framework for blade aerodynamic design under realistic conditions, while considering multiple design parameters. The relationship between the objective function and the design parameters, such as the chord length, maximum chord, and twist angle, were obtained by using the second-order response surface methodology (RSM). Moreover, the identified parameters were organized to optimize the aerodynamic design of the blades. Furthermore, the initial and optimized blade geometries were compared and showed that the performance of the optimized blade improved significantly. In fact, the efficiency was increased by approximately 10%, although its thrust was not varied. In addition, to demonstrate the improvement in the resulting optimized blades, the annual energy production (AEP) was estimated when installed in a specific regional location. The result showed a significant improvement when compared to the baseline blades. This result will be extended to a new perspective approach for a more robust optimal design of a wind turbine blade.

“…Toft et al [16] assessed the structural integrity of a wind turbine using the RSM. Tabatabaeikia et al [17] studied the optimization of a wind turbine based on the computational and experimental method. In that study, as an analytical procedure for the optimization method, the RSM was utilized using multivariate statistical techniques.…”

Günümüzde rüzgar enerjisinden daha fazla faydalanabilmek için, düşey eksenli türbinlerin yaygınlaşması gerekmekte ve kırsal veya şehiriçi her türlü alanda kullanılması gerekmektedir. Dikey eksenli türbin uygulamaları için Savonius ve Darrieus tipi türbinler yoğun bir şekilde kullanılmakta olup, performanslarını arttırmak için Savonius-Darrieus rüzgar türbinleri birlikte kullanım örnekleri görülmektedir. Bu sebeple yapılan çalışmalara göre tek başına kullanılan Savonius veya Darrieus rüzgar türbinlerine kıyasla birlikte kullanımının daha etkili performans sonucunu verdiği araştırmalarda görülmüştür. Dikey eksenli türbinlerin şehiriçi uygulamaları için uygulanabilirliği düşünüldüğünde bu türbinler üzerine daha fazla çalışma yapılması gerekmekte olup ayrıca yeni tasarım araştırma ve geliştirme çalışmaları yapılmalıdır.

“…The channel mass flow rate depends on its position relative to the rotor. The channels directly fed by the inter-polar space (6)(7)(8) show the highest flow rate with a proportion of 12-14 % of the total mass flow through the vent passing through each. In comparison, the minimum flow rate through the channel trailing the IP space (9) only amounts to 4.4 %.…”
