Influence of Separation Gap on the Performance of Savonius Hydrokinetic Turbine
Intelligent and Sustainable Manufacturing: Despite that ocean current energy is one of the promising sources of electricity produced in the ocean, the development of ocean current energy is far behind compared to other ocean energy due to the low efficiency and high cost of installation and ...

Enhancing Savonius Rotor Performance with Zigzag in Concave Surface-CFD Investigation
CFD LettersSavonius, a type of vertical-axis wind turbine (VAWT), is suitable as an appropriate small-scale energy conversion apparatus for regions with relatively low wind speeds, such as Indonesia; however, it exhibits sub-optimal efficiency.

Moderniseeritud Savonius tüüpi tuulik
2013The aim of this graduation work is to study the possibilities of using a new type of wind engine, called modernized Savonius, for producting electricity in regions, where the annual average wind speed is lower than 5...6 m/s. The first part of the work gives an overview how efficciently one can use the energy of the wind by using different types of ...

POWER GENERATING CHARACTERISTICS OF SAVONIUS ROTORS
1966Abstract : 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 ...

The objective of this study is to show the effect of single deflector plate on the performance of combined Darrieus-Savonius water turbine. In order to overcome the disadvantages of low torque of solo Darrieus turbine, a plate deflector mounted in front of returning Savonius bucket of combined water turbine composing of Darrieus and Savonius rotor has ...
