Performance tests on helical Savonius rotors

Renewable Energy, 2009
Conventional Savonius rotors have high coefficient of static torque at certain rotor angles and a negative coefficient of static torque from 135° to 165° and from 315° to 345° in one cycle of 360°. In order to decrease this variation in static torque from 0° to 360°, a helical Savonius rotor with a twist of 90° is proposed.

On the performance analysis of Savonius rotor with twisted blades

Renewable Energy, 2006
The present investigation is aimed at exploring the feasibility of twisted bladed Savonius rotor for power generation. The twisted blade in 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°).

Performance Investigation of a Twisted Savonius Wind Rotor

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences
For human welfare, electrical power is necessary. For many years, there has been a great deal of interest in wind energy because it is a clean, sustainable energy source. Because of its cheaper cost and independence from wind direction, the Savonius vertical axis wind rotor has the advantage of being suitable for certain implementations as an energy ...

A short review on savonius rotor

AIP Conference Proceedings, 2020
The humankind implement a method of energy evolution which means replacement of conventional sources of energy by renewable sources of energy to minimise pollution. Savonius rotor a vertical axis wind rotor used in wind and hydro plant for energy conversion, but the important concern is to build higher efficiency rotor.

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-

Wind tunnel tests on a savonius rotor

Journal of Wind Engineering and Industrial Aerodynamics, 1978
Abstract Tests have been made in a wind tunnel on a number of Savonius rotor configurations in wind speeds of 6–9 m/s. The variables tested were blade aspect ratio, blade overlap and gap and the effects of adding end extensions, end plates and shielding.

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

Design Optimization of Savonius Rotors: An Overview

Applied Mechanics and Materials, 2011
Since the Savonius rotor has a low starting torque and is adaptable for wind in various directions, it has received great attention in the past decades. In this paper, we present an overview of the state of the art in Savonius rotor design, according to three general strategies of design optimization: 1) Optimizing Savonius rotor structural parameters ...
