Abstract
The significant increase in consumption of electricity from fossil fuels encourages the search for renewable energy sources and wind is one of the renewable energy sources which can be utilized using a horizontal axis wind turbine (HAWT). In this case, a drag and lift model with a spiral type was chosen, adjusting to Indonesia's geography with low wind speeds using the wind tunnel testing method. The purpose of this study was to verify the performance of the two nine-blade TASH type spiral models due to the influence of the expansion of the inner diameter of the turbine, namely the normal diameter of 50mm and the expanded diameter of 65mm. The turbine has a rotor length of 120 mm and an outer diameter of 272 mm. Turbine performance is assessed through measured parameters such as actual power value, torque value, rotor speed and power coefficient, torque coefficient, and tip speed ratio (TSR) as non-dimensional parameters. The research was carried out in a series of laboratory tests through a wind tunnel with various wind speeds from 1 m/s to 10 m/s. The test results are then calculated for the Coefficient Power and Coefficient Torque against the Tip Speed Ratio (TSR). From the calculation results produce an effective value with an air gap of 65mm Cp and efficient TSR values at a wind speed of 5 m/s with a rotational speed of 165 rpm with a Ct of 0.31. While the value of Cp and TSR at a wind speed of 5 m/s is 0.072 and 0.23. Keywords : Horizontal Axis Wind Turbine (TASH), Nine Blade Spiral Type, Coefficient Power, Coefficient Torque, Tip Speed Ratio (TSR) Peningkatan konsumsi listrik berbahan bakar fosil yang signifikan mendorong pencarian sumber energi terbarukan dan angin merupakan salah satu sumber energi terbarukan yang pemanfaatannya dapat menggunakan turbin angin sumbu horizontal (HAWT). Dalam hal ini dipilih model drag and lift dengan tipe spiral menyesuaikan dengan geografis Indonesia dengan kecepatan angin rendah dengan metode pengujian melalui wind tunnel. Tujuan dari penelitian ini adalah untuk memverifikasi kinerja kedua model spiral tipe TASH sembilan sudu akibat pengaruh perluasan diameter dalam turbin yaitu diameter normal 50mm dan diameter diperluas 65mm. Turbin memiliki panjang rotor 120 mm dan diameter luar 272 mm. Kinerja turbin dinilai melalui parameter terukur seperti nilai daya aktual, nilai torsi, kecepatan rotor dan koefisien daya, koefisien torsi, dan tip speed ratio (TSR) sebagai parameter nondimensi. Penelitian dilakukan dalam rangkaian uji laboratorium melalui terowongan angin dengan berbagai kecepatan angin dari 1 m/s hingga 10 m/s. Hasil pengujian tersebut kemudian dilakukan kalkulasi untuk Coefficient Power dan Coefficient Torque terhadap Tip Speed Ratio (TSR). Dari hasil perhitungan menghasilkan nilai efektif dengan air gap 65mm nilai Cp dan TSR efisien pada kecepatan angin 5 m/s dengan kecepatan putar 165 rpm dengan Ct yaitu 0,31. Sedang nilai Cp dan TSR pada kecepatan angin 5 m/s adalah 0,072 dan 0,23. Kata kunci : Turbin Angin Sumbu Horizontal (TASH), Sembilan Bilah Tipe Spiral, Coefficient Power (Cp), Coefficient Torque (Ct), Tip Speed Ratio (TSR).
