Abstract
In this study, the author wants to further identify, especially the influence of variations in the number of blades on cylindrical basin-type vortex turbines on their performance. The method used is simulation using CFDs and experimental. Variations in the number of blades used are 5 and 7 blades. The results of this study show that the increase in the number of blades will affect the amount of torque and power produced. In the simulation results, the highest torque in a 5-blade turbine was 13.44 N.m while in a 7-blade turbine, a maximum torque of 14.6 N.m. The results of this simulation were validated by experimental data with a percentage of acceptable errors. The experimental results showed that the highest efficiency occurred in turbine 7 blades of 43.5% and the minimum efficiency occurred in turbines of 5 blades of 40.4%. This study analytically shows that the increase in the number of blades will increase the number of areas in contact with water which will increase the absorption of water energy by turbines.
