Wind power is one of the main sources of renewable energy. New applications of this
technology are currently under development through small vertical axis wind turbines …

In this paper, an attempt has been made to highlight major developments of vertical axis
wind turbines (VAWTs) in the last few decades. The effects of various design parameters …

This work analyses the link between the aspect ratio of a vertical-axis straight-bladed (H-
Rotor) wind turbine and its performance (power coefficient). The aspect ratio of this particular …

The objective of this work was to design, simulate and evaluate the performance of an
innovative hybrid vertical-axis wind turbine (VAWT) for obtaining an extended operational …

Many Modifications have been studied for classical Savonius wind turbines in the blade
shape to improve the power efficiency. Four rotor blade modifications have been studied in …

The performance of a single Savonius turbine depends on the interaction between the
buckets of its rotor. Recent studies also show that interactions between Savonius turbines in …

The Savonius wind turbine is a vertical-axis wind turbine invented in 1930s consisting of a
cylindrical drum with semi-circular blades attached to the drum. It is popular for its simple …

Abstract Drag type Savonius Vertical Axis Wind Turbine (VAWT) has the advantages of the
low total cost, simple manufacture and maintenance. Although the efficiency is low, it is …

Abstract The Savonius Hydro-Kinetic Turbine (SHKT) has a frugal design with the possibility
of easy local manufacturing. Therefore, SHKT is a suitable proposition for off-grid power …

The idea of investigating the fluid dynamic behavior of a ducted Savonius wind turbine
derives from the research about the improvements of Oscillating Water Column Wave …
