“…A few studies have been published on propeller-type axial turbines under 100 mm in diameter. An example is the study by Kurniawan et al, [36] and Nurdin et al, [37], which aimed to determine the electrical power of an axial turbine varying the number of blades from 4 to 8 under different water discharge values. The experimental studies used a horizontal pipe with a turbine installed within it.…”

In-pipe hydraulic turbines are a promising energy-harvesting technology. Recent studies have demonstrated a strong influence of the turbine blade number on the performance of an axial propeller-type turbine. However, limited research has been dedicated to turbine diameters less than 100 mm. Therefore, this research aimed to determine the effect of the number of blades on the hydrodynamic performance of a 75.3 mm diameter axial propeller turbine for in-pipe installation. A parametric numerical study was performed by varying the angular velocity from 1600 to 3800 rpm and the number of blades from 2 to 6. Results identified an inverse correlation between the hydraulic efficiency of the turbine and its blade number and a direct correlation between the pressure head and the turbine torque. Furthermore, the performance showed hydraulic behavior comparable to those found in literature, confirming a similar hydraulic behavior as turbines with diameters exceeding 100 mm. Additionally, the turbine’s internal flow behavior was analyzed by visualizing the vortex structure using the Q-criterion. Lastly, this study provides a deeper understanding of the effect of the number of blades on the hydrodynamic performance of an axial turbine for in-pipe installation.

“…Sementara itu, prinsip kerja generator yaitu merubah daya mekanik menjadi daya listrik saat poros berputar, dimana putaran poros akan memutar rotor terhadap stator sehingga tercipta induksi elektromagnetik pada generator dan menghasilkan listrik. Semakin cepat putaran poros output turbin terhadap generator, maka daya yang dihasilkan juga besar [14]. Hal ini disebabkan karena putaran poros yang cepat menjadikan medan magnet bagian rotor dan stator semakin kuat sehingga daya yang dihasilkan semakin besar.…”

Potential of Indonesian hydropower which has only been utilized 9% has been concern of many researchers. Hydro power, especially on streams with Ultra Low Head (ULH), has become a trend of current research as renewable energy in reducing the energy crisis as a pico scale power plant. ULH which is often identified with horizontal flow can be utilized well with reaction type turbines, which are often used are propeller turbines. Propeller turbines that have high efficiency still need to be investigated and developed in order to produce better output power, especially in horizontal flow. Modification of experimental blades at inlet section of tip and hub of blade is an effort to increase the output power of propeller turbine. Inlet tip angle variations are 19°, 23°, 29°, and 36°, while inlet hub angle variations are 33°, 36°, 40°, and 44° by being tested at a discharge of 13 l/s. This study aims to determine the effect of inlet angle of tip and hub of blade on the performance of turbine on horizontal flow in pipe. The highest results in use of 23° inlet tip and 33° inlet hub are 17.4 watts of electrical power and 50% efficiency.

“…The principle of the generator work converts mechanical power into electrical power when the rotor rotates, so the stator will cause an electric field and generate electricity, so if the test load each parameter and level are the same (5 watts AC), the angular velocity (rpm) value affects the performance. If the turbine rotates faster, the generator power is rising, because when the turbine rotates the generator rotor faster, the electric field produced by the rotor and stator also rising and the generator produces greater electrical power [20].…”
