TL;DR: In this article, the aerodynamic design and performance of VAWTs based on the Darrieus concept is discussed, as well as future trends in design and the inherent socioeconomic and environmental friendly aspects of wind energy as an alternate source of energy.
Abstract: Wind energy is the fastest growing alternate source of energy in the world since its purely economic potential is complemented by its great positive environmental impact. The wind turbine, whether it may be a Horizontal-Axis Wind Turbine (HAWT) or a Vertical-Axis Wind Turbine (VAWT), offers a practical way to convert the wind energy into electrical or mechanical energy. Although this book focuses on the aerodynamic design and performance of VAWTs based on the Darrieus concept, it also discusses the comparison between HAWTs and VAWTs, future trends in design and the inherent socio-economic and environmental friendly aspects of wind energy as an alternate source of energy.

TL;DR: Current and future challenges, feasible solutions and subsequent research prospects are detailed and some key principles that should underlie future changes of wind integrated energy systems are suggested and further research directions are addressed.
88 citations
TL;DR: In this paper, the authors presented a computational fluid dynamics simulation of the Darrieus vertical axis wind turbine with fixed and variable pitch at different solidities and showed that variable pitch blades with high solidities are preferred when the initial self-starting torque is required.

TL;DR: In this paper, the aerodynamic effect of adding a winglet on the blade of a VAWT was studied, and it was shown that the optimal winglet can decrease the tip vortices and improve the blade's power performance by up to 31% at a tip speed ratio of 2.29.
