Dependence of Power Characteristics on Savonius Rotor Segmentation [PDF]
Savonius rotors are large and heavy because they use drag force for propulsion. This leads to a larger investment in comparison to horizontal axis wind turbine (HAWT) rotors using lift forces.

Comparative investigation of Savonius and hybrid H-Savonius wind rotor - an energy and exergy analysis [PDF]
Exergy analysis is a vital tool for wind power development apart from energy analysis. The present study is based on a comparative energy and exergy analysis of Savonius wind rotor and hybrid H-Savonius wind rotor based

Design and construction of Savonius rotor [PDF]
Renewable energy sources have been researched for more than a century now. Wind energy; which is often characterized as an unreliable source of energy, is not unreliable if placed at places with smooth wind currents. Savonius rotor as Vertical Axis Wind Turbine (VAWT) can be used as a standalone power generation device because of its low cost, low cut ...

Aerodynamic Performance Investigations of Savonius Twin-rotor Wind Turbines [PDF]
The aim of this study is to evaluate the aerodynamic efficiency of a Savonius vertical-axis wind turbine. The approach used relies on resolving the Unsteady Reynolds Averaged Navier-Stokes equations (URANS), the turbulence being modeled by the k-ω SST ...
