Abstract

This study aims to design an underwater rotor to utilize the flow rate of the river as a hydroelectric power plant. In this study, an underwater rotor design model will be made with three variations in the number of blades, namely three, six, nine blades. The test parameter observed in this study is the turbine performance through the value of the power coefficient (cp) and the moment coefficient (cm). The method used in this research is an experimental method, namely by making a turbine model with a laboratory scale. The results show that the underwater rotor designed with aspect ratio = 2.0, overlap ratio = 0, end-plate diameter = 1.1d then the barrier plate design with L/D ratio = 1.2 60ยบ provides the highest power coefficient and moment coefficient, namely respectively 0.15 and 0.27 in the design with the number of blades 3 (three)

Abstract

The development of new and renewable energy is currently a top priority for the international community, as energy needs continue to increase while fossil fuels are running low. The Savonius rotor turbine is one of the most widely used turbines but has low efficiency. This study aims to improve the performance of the Savonius turbine by developing a new blade based on airfoil which is simulated in CFD. There are 2 blade models to be simulated, namely the RD-1 model and the RD-2 model, then the simulation results are compared with the conventional blade. The results of the study can be said that the new airfoil-based blade can improve the performance of the Savonius turbine, the increase occurs in the TSR value which is better than the conventional blade. The highest Cp is 0.148 on the RD-2 model blade with a maximum TSR of 0.8
