Modification of the Vertical Axis with Variations in the Number of Blades of the Savonius Wind Turbine
TL;DR: In this paper, the performance of Savonius wind turbines with 2 and 3 blades variables in each turbine blade shape was evaluated on a laboratory scale with a wind source using a fan that is directly opposite the turbine.

Numerical Simulation for the Starting Characteristics of a Wind Turbine
TL;DR: In this paper, the starting characteristics of a wind turbine were analyzed and the force required to stop the turbine was modeled based on friction in relation to the bearing. And the simulation results tend to qualitatively agree with the experimental results for steadily rotating wind turbines in terms of two aspects: (1) the optimal shape has an 20% overlap of the turbine radius, and (2) the larger the gap, the lower the efficiency.
