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

Slotted blade effect on Savonius wind rotor performance

AIP Conference Proceedings, 2020
The increasing needs for energy and the depletion sources of fossil fuels required the use of renewable and clean energy sources. Wind energy is a renewable energy that demand is high right now because it is easily obtained, abundant and environmentally friendly. Wind turbines use the available kinetic energy of the wind to be converted into mechanical

Experimental investigations on single stage modified Savonius rotor

Applied Energy, 2009
Conventional Savonius or modified forms of the conventional Savonius rotors are being investigated in an effort to improve the coefficient of power and to obtain uniform coefficient of static torque. To achieve these objectives, the rotors are being studied with and without central shaft between the end plates.

POWER GENERATING CHARACTERISTICS OF SAVONIUS ROTORS

1966
Abstract : An experimental study of the power generating characteristics of Savonius rotors towed through still water was made. Variations in rotor geometry were investigated. Power absorption, drag and side force were measured on six rotors tested in the towing tank over a range of ratios of rotor vane tip peripheral speed divided by rotor advance ...

Review on Savonius Rotor for Harnessing Wind Energy

Wind Engineering, 2012
Wind machines convert kinetic energy of the wind into usable form of mechanical energy or electrical energy. The Savonius rotor is a vertical axis wind machine which is simple in design. High starting torque characteristics make it suitable for standalone power generation as well as water pumping applications.

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 ...

Theoretical Study on the Flow About Savonius Rotor

Journal of Fluids Engineering, 1984
A method for the two-dimensional analysis of the separated flow about Savonius rotors is presented. Calculations are performed by combining the singularity method and the discrete vortex method. The method is applied to the simulation of flows about a stationary rotor and a rotating rotor.
