“…The height and diameters (top and bottom) of the runner, the inlet and the outlet angles, the helical pitch angle, the number of blades and the position in the basin. The height and diameters of the runner, number of blades, inlet, outlet and helical pitch angles were assigned by considering the available literature [14,20,21,[22][23][24]. During the analysis process, three different positions of the runner were compared.…”

A gravitational water vortex hydraulic turbine (GWVHT) is a low head hydropower technology with a vertical runner for extracting energy from the water vortex. To determine the optimal position (h) of the runner for the hydropower plant efficiency to be increased, a runner in three different positions was compared using computational fluid dynamics (CFD). The position of the runner was a function of the basin height (H). The maximum efficiency (44.15%) was established when the runner was located at 60% of H. The angular velocity associated with the maximum efficiency was 14 rad/s.

“…Sedangkan untuk aliran sungai dengan head yang rendah belum dimanfaatkan secara optimal. Pembangkit listrik berbasis turbin vortex dapat digunakan sebagai solusi untuk daerah yang tidak terjangkau listrik dan memiliki debit air pada head yang realatif rendah [1]. Turbin vortex adalah sebuah pilihan yang baik untuk pembangkit listrik di desa-desa terpencil di mana pasokan jaringan listrik sulit [2].…”

Turbin vortex adalah turbin yang beroperasi dengan memanfaatkan aliran vortex sebagai penggerak sudu-sudu turbin yang kemudian poros turbin dihubungkan ke generator untuk mengkonversi energi mekanis poros kedalam bentuk energi listrik. Salah satu parameter yang berpengaruh terhadap kinerja turbin vortex adalah bentuk sudu. Banyak penelitian tentang sudu turbin vortex yang telah dilakukan, seperti berbentuk profil 3D curve helix dan curved. Pada penelitian ini dilakukan pengujian secara eksperimental sistem turbin vortex menggunakan sudu semi twisted curve dengan sudut sudu 40°, 60° dan 80° diuji pada posisi runner turbin 0 cm atau sejajar dengan dasar saluran air menuju basin. Debit aliran air yang digunakan adalah 0,006 m3/dt. Hasil penelitian menunjukan daya dan efisiensi tertinggi dihasilkan turbin dengan sudu 60° yaitu 7,21 watt dan 28,47 % pada putaran 80 rpm.

The availability of energy has been essential for humanity, which increasingly demands more energy resources to cover its consumption and well-being. Due to the rapid depletion of fossil fuels and climate change, use of alternative energy sources such as non-conventional renewable energy sources is fundamental. Within non-conventional renewable energy sources, small-scale hydroelectric power is an excellent option in the generation of clean energy. Its development has a long useful life with more than 100 years and still with possibilities for new designs and technological adaptations. Among these new designs are the gravitational water vortex hydraulic turbines (GWVHTs). A GWVHT is a run-of-river (ROR) hydropower system that harnesses the kinetic and potential energy of an induced vortex. Its main advantage is the ability to generate energy in low ranges of head and flow. The GWVHT is a new turbine with an efficiency between 17 and 85%, which still needs more research to optimize the geometry of the basin, inlet channel, and runner. This work presents a comprehensive analysis of various aspects of GWVHT such as modeling, optimum sizing, performance, and challenges to establish a starting point for further research. Until now, the studies have proved that the conical basins are better than the cylindrical basins, but they do not identify the dimensions of the geometry. With respect to the runner, the shape or number of blades has been varied, but the investigations show contradictory results.
