Abstract
India ranked 5th in the world for using hydroelectric powerproduction.As of 31 March 2020, India's total installed hydroelectric plant capability was 46,000 MW or 12.3% of its total electricity production capacity. Savonius water turbine is a useful prime mover to convert hydraulic power to electric power. It has been proven that the twisted blade of the blade has better performance than others. In the present study, the Numerical method has been used to analysis the 60° twist angles from top to bottom of the blade. The aspect ratio is taken as 1. Research is carried out for the variable load on the shaft for the same flow rate and twist angle. In the present numerical investigation, the considered angular velocity is 1 rad/s, 5 rad/s, 10 rad/s, 15 rad/s, 20 rad/s, 30 rad/s, 40 rad/s, 50 rad/s, 60 rad/s, 70 rad/s, 80 rad/s, 90 rad/s, 100 rad/s and 150 rad/s. The numerical analysis shows that the higher the load on the shaft, the lower the power generated by the turbine and vice-versa.
