Abstract

Saat ini teknologi energi terbarukan semakin gencar dikembangkan. Hal itu dikarenakan sumber energi fosil semakin menipis, serta efek samping dari penggunaan energi fosil sangat merugikan lingkungan sekitar. Turbin vortex merupakan salah satu teknologi pemanfaatan sumber energi terbarukan, dimana turbin ini mampu beroperasi pada head rendah, yaitu 0,7 m – 3 m, serta tidak membutuhkan kapasitas yang besar untuk membangkitkan daya listik. Sehingga turbin ini mudah diimplementasikan di pemukiman yang dialiri air. Pada penelitian ini dilakukan secara numerik pengaruh sudut inlet dan sudut stagger runner terhadap unjuk kerja turbin vortex, dan intensitas aliran vortex. Metode analisis numerik menggunakan computitaional fluid dynamic (CFD) dengan software SolidWokrs. Selanjutnya dilakukan validasi hasil simulasi dengan hasil experimen. Penelitian dilakukan untuk menganalisis intensitas aliran vortex pada variasi sudut inlet basin 0o, 5 o, 10 o, dan 15 o, dimana sudut inlet basin 10o mempunyai intensitas votex paling baik yaitu 0,027 m2/s. Pada basin 10o, dilakukan analisis performa turbin vortex pada variasi sudut stagger runner 0o, 10o, 20o, dan 25o. Dapat disimpulkan bahwa, turbin vortex dengan sudut stagger runner 10o mempunyai performa paling baik, yaitu effisiensi sebesar 13,046% dan koefisien power sebesar 0,13, serta menghasilkan torsi sebesar 0,635 Nm.

Currently, renewable energy technology is increasingly being developed. This is because fossil energy sources are dwindling, and the side effects of using fossil energy are very detrimental to the surrounding environment. The vortex turbine is one of the technologies for utilizing renewable energy sources, where this turbine is capable of operating at a low head, which is 0.7 m – 3 m, and does not require a large capacity to generate electrical power. So that this turbine is easy to implement in settlements that are flowing with water. In this research, numerically the influence of the inlet angle and the stagger runner angle on the performance of the vortex turbine, and the intensity of the vortex flow. The numerical analysis method uses Computational fluid dynamics (CFD) with SolidWorks software. Furthermore, the simulation results were validated with experimental results. The study was conducted to analyze the intensity of vortex flow at the variation of the inlet basin angle of 0o, 5o, 10o, and 15o, where the inlet basin angle of 10o has the best votex intensity of 0.027 m2/s. In the 10o basin, an analysis of the performance of the vortex turbine was carried out at various stagger runner angles of 0o, 10o, 20o, and 25o. It can be concluded that a vortex turbine with a stagger runner angle of 10o has the best performance, namely an efficiency of 13.046% and a power coefficient of 0.13, and produces a torque of 0.635 Nm.
