Vertical axis wind turbines (VAWTs) have received growing interest for off-shore application
and in the urban environments mainly due to their omni-directional capability, scalability …

The performance of a Savonius wind turbine with constant cross-sections is examined by
means of quasi 2D flow predictions executed in ANSYS CFX. Simulations were performed in …

This paper introduces an optimization procedure of a modified Savonius rotor with different
convex and concave sides to maximize the power efficiency. A series of transient …

Addressing the energy crisis and global warming issues would entail urgent development of
efficient and environmentally-benign power generation systems to mitigate the future clean …

There are many advantages of vertical axis wind turbines (VAWTs) compared with horizontal
axis wind turbines (HAWTs). Research has shown that VAWTs are more suitable for …
