ABSTRACT
Nonrenewable energy sources are limited and harmful to the environment. The use of a Savonius rotor to harness one of the renewable energy sources, hydrokinetic energy, is investigated in this study. The power output of the Savonius rotor is low; therefore, a ‘C’ shaped deflector was employed on the rotor’s upstream side to boost power output. The experimental analysis was done to find the best position for the ‘C’ shaped deflector in this work. The experiments were conducted in two stages: keeping the X-coordinate fixed and varying Y-coordinates. After getting maximum power output for Y-coordinate, the X-coordinate was optimized. The results show an increase in rotor power output by 23% and a decrease in the power coefficient for the best deflector position.
