Abstract

Darrieus helical turbine is a type of CFWT (Cross Flow Water Turbine) turbine which is the development of the Darrieus Turbine for wind with the advantage of having a stable torque at various current speeds and can rotate at low current speeds. The objectives of this final project are (1) To make 5 models with 3 blades of Darrieus helical turbine based on NACA 0012 with various blade angles; (2) To test the performance of Darrieus helix turbine model with variations in blade angle; (3) to analyze the performance of Darrieus helix turbines and comparing the variations of the blade angle made in order to obtain the best performance. The final project method includes the design of the Darrieus helical turbine design, manufacture and assembly of the turbine, the testing phase, and the processing and data analysis stages. The test was carried out at the flow velocity of 0,55-0,58 m/sec with a variation of the blade angle of 0°, 10°, 20°, 30°, 40°. The wind turbine performance test analysis is based on the calculation of turbine efficiency. The test results show that the Darrieus helical turbine has the best efficiency of 29,84% at a speed of 0,55 m/s with a blade angle of 30° and then efficiency is 20,41% at a speed of 0,58 m/s with a blade angle of 20°.
