“…Zemamou et al [9] carried out studies to increase the power coefficient of the classical savonius rotor (classic savonius Cp range varies between 0.1 and 0.25) and because of the geometric improvements they made, they increased the power coefficient to 0.273. Gül and Kolip [10] achieved better results with the split blade designs of the Savonius rotor that they designed, which open and close according to the wind direction, compared to the power coefficient of the classical Savonius rotor (Cp = 0.38) and an improvement of 40 percent was observed compared to the other designed models. Jeon et al [11] investigated the performance change in the wind tunnel by adding caps in different shapes (4 types) to savonius rotors with helical blade structure and changing the diameters of these end plates.…”

In this study, Savonius-type wind turbine rotors with the same front view area were produced with 3D printers by changing their aspect ratios, and then both experimental and numerical analyzes were carried out according to them attaching end plate and without end plate situations. The wind tunnel in the university was used in the experimental analysis. For numerical analysis, rotors and wind tunnels modeled in CAD program were analyzed in Ansys Fluent program. The analyzes made are for imaging purposes only, and the results in the experimental analyzes are accepted as correct. The reduction of aspect ratios in the uncapped analyzes decreased the overall efficiency, but the opposite effect was observed when the analyzes were repeated with the end plate. In addition, while negative pressure was observed in the rotors made without cover (bare case) in the digital images, this situation was not seen in the analyzes made with the end plate.

“…The design process of the aircraft directly effects critical flight functions such as cruising distance, speed, flight comfort, number of passengers or cargo it can carry, altitude, operational space and maneuverability [1,2]. All these components effect the fuel consumption [3] finally which is directly effected by the geometry of the wing [4].…”

While the aircraft is moving in the opposite direction of the flow in the air, the wind resistance and the moment effect due to this resistance negatively affect the flight performance. In design studies, it is aimed to increase aerodynamic performance by minimizing these two negative factors. In this study, the effect of wing cross section and three-dimensional airfoil on aerodynamic performance is investigated numerically. Within the scope of this study, to reach the intended design, biomimetic design approach was used and new-wing designs were created to mimic the bird species’ wings, which have the highest aerodynamic performance in nature. Based on the literature search for two-dimensional wing section selection, it was seen that the most preferred sections were identified and compared with the wing section of the Cessna 172 aircraft (NACA2412) in flow analysis. In the flow analysis conducted in the XFLR5 program, the aerodynamic performances of the wing sections at Reynolds value and angle of attack were investigated. According to this analysis, the aerodynamic efficiency of the NACA2412 section was higher than that of the other sections. In the three-dimensional flow analysis, biomimetic wing designs and the wing of the Cessna 172 aircraft were examined in the XFLR5 program at a cruising speed and angle of attack. It was observed that the aerodynamic efficiency of the wing design, which is inspired by the albatross, is higher than the other designs. Owing to the flow analysis, the albatross wing design provided 6.26% improvement in the lift coefficient, 15.73% in drag coefficient and 15.16% improvement in the glide ratio compared to the Cessna 172 aircraft wing design. For structural analysis, the pressure values obtained from the flow analysis results were used as the load distribution on the wing. In the designs created using the same material, it was observed that the weight of the wing inspired by the albatross was 34.156% less weight and 50.902% less deformation value obtained compared to Cessna 172 aircraft.

“…Since blade geometry has an effect on the load that applied to the blade, geometric design also appears to be an important factor towards eliminating mentioned challenges. Modern wind turbines are grouped according to the rotation orientation of turbine blades in two types: horizontal-axis wind turbines (HAWT) and vertical-axis wind turbines (VAWT) [4]. The geometry and dimensions of the blades affect the performance of the HAWT blades [5].…”

Sürdürülebilir enerji kaynağı olarak rüzgâr türbinleri rüzgârın kinetik enerjisini elektrik enerjisi dönüştüren sistemlerdir. Rüzgâr türbinlerinde kanat profillerinin geometrisi kanat yüzeyinde oluşan aerodinamik kuvvetlerin büyüklüğünü etkilemektedir. Bu çalışmada farklı rüzgâr hızlarında (4-16 m/s) standart NACA 63-415 kanat profilinin geometrik şeklinin kanat performansına etkisi SST k-ω türbülans modeli ile ANSYS Workbench programını kullanarak araştırılmıştır. Standart kanat profilinin HAD sonuçları deneysel çalışmayla doğrulanmıştır. Birinci adımda, standart kanat profilinin yüzeyinin şekli değiştirilerek NCAY30 ve NCAYÜY 30 kanat profilleri üretilmiştir. İkinci adımda, katı kanat modelleri kanat boyunca 1 m aralıklarla 7° hücum açısı, 7 kanat uç hız oranı ve 20 m kanat uzunluğu için optimum veter uzunlukları ve bağlama açıları hesaplanarak SOLIDWORKS programı kullanılarak katı kanat modelleri oluşturulmuştur. Maksimum Cp değeri 0,511 olarak 16 m/s rüzgâr hızında NCAYÜY 30 kanat modeli ile elde edilmiştir ve bu kanat modeli standart NACA 63-415 kanat modeline göre Cp değerini %10,62 artırmıştır. NCAYÜY 30 kanat modeli için maksimum kanat hızı standart kanat modelinden %7,2 daha fazladır. Bu çalışmada geliştirilen iki aşamalı yöntem rüzgâr türbini kanat tasarımı ile ilgili gelecekteki araştırmalara yardımcı olacağı düşünülmektedir.
