“…The realizable torque, TR, from a wind turbine is obtained by: TR=CT(1/2) ρ A V 2 rm (5) CT = TR / (1/2) ρ A V 2 rm (6) where rm=(D/2)√[ (1 + λ 2 ) /2] (7) The power coefficient, CP is a function of wind turbine rotor characteristics and the working tip speed ratio of the turbine; it can be expressed in the following form. CP = PR / (1/2) ρ A V 3 (8) Where, PR is the realized power from a wind turbine and is obtained as PR= TR ω (9)…”

The field of wind energy has made significant progress, yet there is always room for improving efficiency and the energy extracted from horizontal axis wind turbines HAWTs. There is interest in new renewable energies, including wind energy. This study aims to investigate the effect of trailing edge flap on the performance of the turbine at different numbers of blades, different blade angles, and flap angles. Therefore, an experimental setup includes a model of wind turbine was constructed. The performance of a HAWT model with trailing edge flaps added is examined in this research using the findings of wind tunnel tests. A model with two, three, and six-bladed rotors with a diameter of 260 mm was employed for the wind tunnel tests. The wind turbine model is tested at various blade angles and tip speed ratios. The model was initially tested at various blade angles without any flaps, β, of 10 o , 15 o and 20 o , with two, three, and six-bladed rotors and secondly the wind turbine model was tested with additional trailing edge flaps with flap angle, α, of 40 o , 50 o and 60 o . It was found that the use of trailing edge flaps can improve the HAWT performance.

“…They found that an efficient blade shape depends on the performance of the selected airfoils. Widiyanto et al [3] held an analysis for the performance of a SHAWT with airfoil NACA 4412. The analysis examined wind flow around the airfoil using the integral boundary layer formulation and the potential flow panel approach.…”

“…It should be explained that the SG6042 and SG6043 airfoils were designed by Giguere and Selig [30] for application in SWT blades. Although the NACA4412 airfoil was initially designed for aviation purposes, because of the simplicity of its manufacturing process due to its flat pressure side, in recent years, it has attracted lots of attention from researchers working on SHWT blades [31,32]. Figure 1 shows the geometry of the selected airfoils in Cartesian coordinates.…”

The blade number and airfoil profile effects on the blade shape of a small horizontal-axis wind turbine (SHWT) were investigated. For this purpose, the NACA4412, SG6042, and SG6043 airfoils, as well as 2, 3, and 4 blades, were considered. Then, two optimization processes were used: first, the blades were designed to maximize the power coefficient ( C p ), and then a multiobjective optimization that included both maximizing C p and maximizing the starting torque ( Q s ) was employed. The differential evolution (DE) algorithm was employed to perform the optimization, and the blade element momentum aerodynamic approach was used to conduct the relevant computations. Also, to ensure the performance of the optimal blades, the computational fluid dynamics method was employed as well. The findings revealed that regardless of the number of blades and the type of airfoil, raising the twist angle ( θ p ) and chord length ( c ) along the radial direction of the blade, especially at the root part, helps increase the Q s . It was observed that increasing the number of blades does not have a significant effect on the θ p distribution of the selected airfoils, but the c of the blades fitted with all three airfoils decreases. Regardless of the number of blades, while the geometry of blades utilizing the NACA4412 and SG6042 airfoils are close to each other, the blade with the SG6043 airfoil has the shortest c , which reduces the generated Q s of blades fitted with this airfoil. The results also establish that by increasing the number of blades from 2 to 3, the power coefficient ( C p ) of the blades fitted with all three airfoils increases, but by further increasing the number of blades from 3 to 4, the change in C p completely depends on the airfoil profile.

Kondisi geografis Kampus JGU Depok mempunyai sumber daya alam dengan potensi yang baik untuk pengembangan energi terbarukan. Energi angin merupakan salah satu pemanfaatan energi terbarukan yang memiliki potensi sangat besar untuk dikembangkan. Penggunaan sumber pembangkit tenaga listrik yang digunakan masih cenderung menggunakan sumber daya alam yang akan habis dipakai dalam beberapa puluh tahun mendatang. Skripsi ini dibuat dengan memanfaatkan sumber daya alam yang dimiliki kampus JGU Depok. Sumber daya angin ini dapat dimanfaatkan untuk menghasilkan listrik, dengan menggunakan sebuah turbin angin sehingga penelitian ini merupakan menganalisa sebuah pembangkit listrik tenaga angin (PLTB) sejalan dengan pemerintah dengan mengembangkan energi terbarukan tetap dengan dilakukannya skripsi ini merupakan suatu langkah awal guna memberikan dampak besar kedepannya yaitu menjadikan kampus C JGU ini menjadi kempus mandiri energi. Untuk itu, kami akan menerapkan Pembangkit Listrik Tenaga Angin Kapasitas 800 Watt sebagai Penerang Area rooftop Kampus C JGU dengan harapan dapat bermanfaat untuk Pihak Kampus C JGU.
