Abstract

Penelitian ini dilakukan kajian eksperimen dengan memvariasikan stagger angle pada S/d = 0,75 konstan. Bentuk sudu turbin Savonius menggunakan persamaan myring dan menempatkan silinder sirkular pada daerah advancing. Kajian eksperimen dilakukan pad sudu kombinasi myring n=1 pada sisi cekung dan n=2 pada sisi cembung. Silinder berdiameter 12 cm ditempatkan pada sisi advancing dengan memvariasikan sudut stagger 0o, 15o, 30o, 45o, 60o, 75o dan 90o. Model uji berukuran tinggi dan diameter masing-masing sebesar 0,40 m dan flowing tank memiliki ukuran lebar dan tinggi masing-masing 1 m dan diuji pada arus 0,2 m/s. Hasil diperoleh bahwa silinder sirkular diletakan pada sisi advancing pada stagger γ = 60º menghasilkan Cp tertinggi 0,1515 atau meningkat sebesar 10,27% dibandingkan dengan tanpa silinder.

Abstract

The wind energy is the one of the renewable energy to produce the power using turbine. The Savonius turbine have lower performance compared to the other. In this work, the method used is the experimental stu using the wind tunnel to flow air go to the Savonius turbine. The model used is a conventional Savonius wind turbine by adding cylinder installed in front of advancing area with a diameter of 0.4 m and a height of 0.4 m and ds/d of 0.1, 0.2, 0.3, and 0.4 with the rotation of 20 rpm at a stagger angle of 0°, 30°, 60°, and 90°. The experiment is kept constant at the velocity of 7 m/s. This work objective will determine the torque and power coefficient by varying the diameter and stagger angle. The results show that the biggest performance decreased was about 40% in the variation of ds/d of 0.3 with a stagger angle of 0°. The best results show that the wind turbine performance occurred the highest improvement in about 12% at the variation of ds/d = 0.4 with a stagger angle of 60°.
