TL;DR: In this article, a patterned Savonius vertical axis wind turbine farms are developed for renewable energy generation, consisting of multiple clusters with scaled geometrical ratios of the three turbine cluster.
Abstract: An efficient triangular shaped three co-rotating Savonius turbine cluster arranged in close proximity shown in Ref. [1] enhances the average output power of its three turbines up to 34% compared to their isolated counterpart. In this study, patterned Savonius vertical axis wind turbine farms are developed for renewable energy generation. The farms consists of multiples of triangular efficient three turbine clusters. The three turbine cluster has a triangular shape and the turbines inside the cluster are arranged in a close proximity to enhance their average output power. The efficient Savonius wind turbine farms are developed using the enhanced three co-rotating triangular turbine cluster of Ref. [1] as the building unit. The developed farms consist of multiple clusters with scaled geometrical ratios of the three turbine cluster keeping the same topology of the cluster. This resulted in patterned farms that have the same power enhancement ratio of the three turbine cluster. Numerical simulations of farms that consist of nine and twenty-seven turbines confirm the enhancement and the pattern progression for larger farms. Numerical results are obtained using Fluent code.

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: In this paper, a Savonius-style vertical axis wind turbine with direct discharge flow capability in order to ventilate buildings was designed and validated using available experimental results in literature, and two design modifications, variations in cross-section with respect to the height of rotor and conical shaft in the middle of wind rotor are proposed.
