TLDR
The Savonius rotor can develop a relatively high torque at low rotational speeds and is cheap to build, but it harnesses only a small fraction of the wind energy incident upon it as mentioned in this paper.About:

On the performance analysis of Savonius rotor with twisted blades
Ujjwal K. Saha,M. Jaya Rajkumar +1 more
TL;DR: In this paper, a three-bladed rotor system has been tested in a low speed wind tunnel, and its performance has been compared with conventional semicircular blades (with twist angle of 0°) on the basis of starting characteristics, static torque and rotational speed.

An experimental and numerical study on the improvement of the performance of Savonius wind rotor
Burçin Deda Altan,Mehmet Atılgan +1 more
TL;DR: In this article, a curtain has been designed to increase low performance of the Savonius wind rotor, a type of vertical-axis wind rotor and the effect of this curtain on the static rotor performance has been analyzed both experimentally and numerically.
Journal ArticleDOI
An experimental study on improvement of a Savonius rotor performance with curtaining
TL;DR: In this article, a new curtaining arrangement was introduced to improve the performance of Savonius wind rotors by placing a curtain in front of the rotor to prevent the negative torque opposite the rotor rotation.

Vertical-axis wind turbine: A modified design
S.A. Tabassum,S.D. Probert +1 more
TL;DR: In this article, parts of each Bach-type blade of a conventional Savonius rotor have been replaced by four flaps, which open when moving into the wind, so the drag on the blade is then reduced.
