Development of efficient vertical axis wind turbine clustered farms

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.
