On the Performance of the Savonius Wind Turbine

Journal of Solar Energy Engineering, 1989
An extensive wind tunnel test program is described which assesses the relative influence of system parameters on the Savonius rotor performance. The parametric study leads to an optimum configuration with an increase in efficiency by around 100 percent compared to the reported efficiency of ≈12–15 percent.

Numerical and experimental study of a helical Savonius wind turbine and a comparison with a two-stage Savonius turbine

Renewable Energy, 2020
Abstract In this paper, the aerodynamic performance of a helical Savonius rotor model with 180° twisted blades is investigated numerically and experimentally. It is also performed a comparison of results with a two-stage Savonius with similar parameters. The experimental study is conducted in the aerodynamic tunnel Prof.

Partially-blocked savonius rotor

Applied Energy, 1992
Abstract A Savonius rotor can develop a relatively high torque at a low rotational speed. It is cheap to build, but harnesses only a small fraction of the wind energy incident upon it. One proposal for augmenting the energy-harnessing effectiveness was to employ a V-shaped deflector mounted upstream of the rotor, apex into the wind, so that the air-

Performance Characteristics of Vertical-Axis Off-Shore Savonius Wind and Savonius Hydrokinetic Turbines

Volume 10: Ocean Renewable Energy, 2018
The rise in energy demand, climate change and depletion of fossil fuel, encourages the researchers to find a solution to the scarcity of clean energy. Therefore, the extraction of energy from renewable energy sources has become a topic of interest in the past few decades across the globe.

Performance estimation of Savonius wind and Savonius hydrokinetic turbines under identical power input

Journal of Renewable and Sustainable Energy, 2018
In the context of energy crisis, extensive depletion of fossil fuel, and climate change, the vertical-axis Savonius-type wind or hydrokinetic turbines appear to be promising candidates to extract energy from wind or free-flowing water because of their superior self-starting capability and design simplicity.

On the torque mechanism of Savonius rotors

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract The aerodynamic performance and the flow fields of Savonius rotors at various overlap ratios have been investigated by measuring the pressure distributions on the blades and by visualizing the flow fields in and around the rotors with and without rotation. Experiments have been performed on four rotors having two semicircular blades but with

Layout optimization of Savonius-turbine clusters and investigation of linear Savonius wind farms

2019
Vertical axis wind turbines (VAWTs) are compact, costless, less noisy and operate at low cut-in wind speed, which are promising for applications in urban environment. Their performance could be further improved by coupling with each other constructively in clusters.

Savonius rotor as a part of complex systems

Journal of Sound and Vibration, 2019
Abstract Savonius rotor is considered as an element of mechanical or electromechanical systems. An empirical approach is proposed for describing the aerodynamic torque basing on available data from physical and computational experiments. A stand-alone wind power generator based on the Savonius rotor is examined where the electromechanical interaction
