Peningkatan Kinerja Rotor Savonius Dengan Mengembangkan Sudu Baru Berbasis Airfoil

Abstract

<p><em>The development of new and renewable energy is currently a top priority for the international community, as energy needs continue to increase while fossil fuels are running low. The Savonius rotor turbine is one of the most widely used turbines but has low efficiency. This study aims to improve the performance of the Savonius turbine by developing a new blade based on airfoil which is simulated in CFD. There are 2 blade models to be simulated, namely the RD-1 model and the RD-2 model, then the simulation results are compared with the conventional blade. The results of the study can be said that the new airfoil-based blade can improve the performance of the Savonius turbine, the increase occurs in the TSR value which is better than the conventional blade. The highest Cp is 0.148 on the RD-2 model blade with a maximum TSR of 0.8</em></p>

Pengaruh Ratio Overlap Sudu Terhadap Performa Turbin Air Poros Horizontal Savonius

“…Salah satu solusi untuk mengatasi permasalahan ini adalah dengan mengembangkan energi terbarukan, seperti energi air, angin, surya (Burek, S. and Hankey, W.1980) & (Rendi, R. and Hartadi, B., 2018). Meskipun teknologi energi terbarukan telah berkembang pesat dalam beberapa dekade terakhir, namun pemanfaatannya masih belum optimal di beberapa negara & (Rendi, R., Ihsan, S. and Ma'arif, S., 2020). Salah satu jenis energi terbarukan yang belum banyak dimanfaatkan adalah energi air (Bhattacharya, S., Saha, U. K., & Bandyopadhyay, S. 2015) & (Rendi, R. and Herlina, F., 2022).…”

“…(Hartadi, B., 2022) & (Gandhidasan, P., & Mohanraj, M. 2016). Turbin air Savonius memiliki bentuk seperti setengah silinder dengan dua sudu membentuk huruf "S" dan beroperasi dengan prinsip aksi dan reaksi (Jain, R., & Gupta, N. K. 2017) & (Rendi, R., Hartadi, B., Firman, M. and Irfansyah, M., 2022). Keunggulan dari turbin air Savonius adalah kemampuannya untuk menghasilkan listrik dari arus air rendah dan bisa digunakan pada berbagai jenis sumber air seperti sungai, air laut, dan air limbah (Kamoji, 2013) melakukan penelitian mengenai pengaruh rasio overlap sudu pada turbin aliran air Savonius.…”

Experimental study of small hydro turbine propeller performance with a variety of blade angles of attack

“…The propeller turbine is a hydro-turbine suitable for low heads such as irrigation canals and rivers [13]. The efficiency of the power generated by the propeller turbine is about 40 -60% of the input power used to drive the turbine [14] [15].…”
