TLDR
In this paper, the influence of the installation of guide vane on the performance of Savonius wind turbine and the number of rotor blade which produces the most maximum performance was analyzed and the results indicated that rotor with three blades can give better performance than rotor with two and four blades.Abstract:
The objectives of research were to understand the influence of the installation of guide vane on the performance of Savonius wind turbine and to acknowledge the number of rotor blade which produces the most maximum performance. There are three variations for the number of rotor blade, which are 2, 3 and 4 blades on the range of wind speed are 4-7 m/s. Result of research indicated that rotor with three blades can give better performance than rotor with two and four blades. Rotor with guide vane has produced better performance in power coefficient rate for 0,3638 at wind speed 5 m/s, while rotor without guide vane can only provide power coefficient for 0,2595 at similar wind speed 5 m/s.read more

Optimization of Savonius turbines using an obstacle shielding the returning blade
TL;DR: In this paper, the position of an obstacle shielding the returning blade of the Savonius turbine and possibly leading to a better flow orientation toward the advancing blade is optimized. And the optimization process takes into account the output power coefficient as target function, considers the position and the angle of the shield as optimization parameters, and relies on Evolutionary Algorithms.
