Unlike horizontal axis turbines, the Darrieus-type wind turbines have less efficiency and suffer from the self-starting inability. The effects of fixed and variable blade pitch angle as an idea for improving the performance ...

The Darrieus wind turbine is a type of vertical-axis wind turbines which, in spite of its simple structure,

is very complex to analyze. In terms of aerodynamics, Darrieus VAWTs have properties which tend to

make ...

Vertical axial wind turbines are the most commonly used turbines in residential and urban
areas. This paper investigates the effect of combining Darrieus and Savonius wind turbines
on power output and introduces a ...
