Abstract

Penggunaan turbin angin sebagai salah satu solusi energi terbarukan semakin berkembang, khususnya dalam pemanfaatan aliran udara buangan dari sistem ventilasi di industri. Penelitian ini bertujuan untuk menganalisis kinerja turbin angin sumbu horizontal (HAWT) dan melakukan variasi jumlah stage (tahapan turbin) yang terpasang pada aliran udara buangan dari exhaust fan di PT Amerta Indah Otsuka. Metode yang digunakan dalam penelitian ini adalah studi numerik berbasis simulasi Computational Fluid Dynamics (CFD) untuk mempelajari pengaruh variasi jumlah stage terhadap efisiensi dan daya output turbin. Penelitian diawali dengan menganalisis performa turbin angin eksisting (tiga stage), Kemudian dilakukan validasi yang akan dijadikan acuan untuk melakukan simulasi pada konfigurasi selanjutnya yaitu dua stage dan satu stage. Perhitungan efisiensi total (kehilangan energi mekanis dan elektris) berdasarkan referensi sebesar 76.71%. Hasil penelitian menunjukkan bahwa turbin angin eksisting menghasilkan torsi sebesar 0,711 Nm, daya keluaran 20 watt dan efisiensi 23.3%. Pada konfigurasi dua stage menghasilkan kinerja terbaik dengan torsi 1.118 Nm, daya keluaran 31.42 watt dan efisiensi sebesar 33.3%. Sementara itu pada konfigurasi satu stage menghasilkan torsi 0.467 Nm, daya keluaran 13.12 watt dan efisiensi 15.29%. Dari hasil analisis menggunakan simulasi Computational Fluid Dynamic (CFD) didapatkan kesimpulan bahwa dari ketiga konfigurasi tersebut (tiga stage, dua stage dan satu stage), Konfigurasi dua stage menghasilkan daya output tertinggi dibandingkan dengan konfigurasi lainnya, diikuti dengan konfigurasi tiga stage dan satu stage.

The use of wind turbines as one of the renewable energy solutions is growing, especially in the utilization of exhaust air flow from ventilation systems in industry. This study aims to analyze the performance of horizontal axis wind turbines (HAWT) and vary the number of stages (turbine stages) installed in the exhaust air flow from exhaust fans at PT Amerta Indah Otsuka. The method used in this study is a numerical study based on Computational Fluid Dynamics (CFD) simulation to study the effect of variations in the number of stages on turbine efficiency and output power. The research began by analyzing the performance of the existing wind turbines (three stages), then validation was carried out which will be used as a reference to simulate the next configuration, namely two stages and one stage. Calculation of total efficiency (mechanical and electrical energy loss) based on a reference of . The results show that the existing turbine system produces a torque of 0.711 Nm, an output power of 20 watts and an efficiency of 23.3%. In the two-stage configuration76.71%, it produces the best performance with 1,118 Nm of torque, 31.42 watts of output power and an efficiency of 33.3%. Meanwhile, in the single-stage configuration, it produces 0.467 Nm of torque, 13.12 watts of output power and 15.29% efficiency. From the results of the analysis using Computational Fluid Dynamic (CFD) simulation, it was concluded that of the three configurations (three stages, two stages and one stage), the 2-stage configuration produced the highest output power compared to the other configurations, followed by the three-stage and one-stage configurations.
