| Summary: | Electricity plays an important role in today's technological developments. Waterwheel is a medium for generating electrical energy through hydropower. The performance of a waterwheel can be affected by several parameters, including the shape of the water flow velocity, the geometry of the blades, and the number of blades installed. So this research discusses the description of the value of the water velocity in the river below Sigay's waterfall and the effect of the number of blades and the shape of the blades on the rotating speed of the wheel. Measurement of the velocity of water flow using the buoy method, money then the average velocity value is used as the velocity inlet in this study. Undershot waterwheel with flat and curved blades measuring 30 x 40 cm submerged in water as deep as 25 cm was visualized using the CFD (Computational Fluid Dynamic) method using Ansys Fluent software. The results of the measurement of the velocity of the water showed that the average speed of water was (40.38 ± 0.671) cm / s. Whereas the CFD simulation results show that the number of blades and the shape of the blades influence the wind speed. The angular velocity on flat blades increases in the number of blades 6 to 10 but decreases when 10 to 15, and for curved blades it increases at the number of blades 6 to 8 but decreases at 8 to 15, so there is a maximum angular velocity value for a certain number of blades, namely 10 pieces for flat blades with a value of 7.395 rpm and 8 pieces for curved blades with a value of 8.761 rpm. Curved blades produce a greater angular speed than flat, i.e. curved blades are in the range of 8 rpm and flat blades are only in the range of 7 rpm. |
