Abstract

Penelitian dilakukan untuk mengetahui pengaruh dari soliditas dan blade aspect ratio terhadap kinerja turbin hidrokinetik vertikal tipe-H Darrieus. Penelitian ini menggunakan 3 variasi soliditas 0,48; 0,6; dan 0,75 dan untuk blade aspect ratio digunakan variasi 4, 5, dan 6,25. Penelitian dilakukan pada flume tank dengan kecepatan aliran yaitu 0,29m/s; 0,34m/s; dan 0,39 m/s. Hasil dari eksperimen ini menunjukkan bahwa soliditas 0,6 memiliki kinerja terbaik dibandingkan dengan soliditas lainnya. Terjadi peningkatan nilai koefisiensi performansi (C_p) sebesar 83,3% dari soliditas 0,4 menuju 0,6. Kemudian terjadi penurunan nilai C_p sebesar 6,81% ketika ditingkatkan menuju soliditas 0,75. Pada blade aspect ratio menunjukan peningkatan nilai C_p seiring dengan peningkatan blade aspect ratio dengan peningkatan sebesar 7,31%. Passive flap dapat meningkatkan nilai C_p turbin hingga 17,3%.

The research was conducted to investigate the effects of solidity and blade aspect ratio on the performance of a vertical-axis hydrokinetic turbine of the H-Darrieus type. The study utilized three variations of solidity, namely 0.48, 0.6, and 0.75, and for the blade aspect ratio, variations of 4, 5, and 6.25 were employed. The experiments were carried out in a flume tank with flow velocities of 0.29 m/s, 0.34 m/s, and 0.39 m/s. The results of this experiment indicate that a solidity of 0.6 exhibited the best performance compared to other solidity values. There was an increase in the coefficient of performance (
