Abstract

The limitations of fossil energy sources are one of the most fundamental energy problems. Therefore, it is necessary to make power plants with alternative sources that are environmentally friendly and affordable. One effort that can be done is using water energy to drive turbines. This study aims to determine the effect of blade angle on the total power and efficiency produced by the hydrofoil water turbine. In this study using a two-stage hydrofoil turbine with NACA 64-212 standard blade. The turbine blade angle is varied by 4, 6, and 8 degrees. Water discharge is varied by 40, 50, and 60 L/s. The results show that the largest total power is 3.046 Watt, achieved at a 4-degree blade angle with a water discharge of 60 L/s. And the highest efficiency is 11.22%, achieved at a 4-degree blade angle with a water discharge of 40 L/s.
