Savonius rotor is seldom applied in wind power generation system due to its lower aerodynamic efficiency. But studies about Savonius rotor still continued since the rotor structure is simpler and the manufacturing cost is lower. Computational fluid dynamics simulations are adopted to compare the output power, torque and power coefficient (Cp) for the conventional two-blade Savonius rotors with three different aspect ratios but the same swept area under the same wind condition to investigate the optimum blade configuration. The rotor with tall and thin configuration is found to have the maximum output power and Cp. The rotor with short and wide configuration has the maximum torque but the minimum Cp. The current result suggests the optimum aspect ratio is 4/1. The influence related to the circular cover plates at two ends of rotor was studied also. It reveals that both the torque and power coefficient for Savonius rotor with end-plates are larger than that without end-plates.
