Abstract

we showed that interactions between two co-rotating Savonius turbines in parallel and oblique clusters and three turbines in triangular clusters enhance the output power of individual rotors compared their isolated counter-parts. In this paper similar studies for two counter-rotating Savonius turbines in parallel and oblique clusters and three turbines in triangular clusters is performed by numerical simulation. The computational results are compared with the co-rotating clusters to determine the optimum cluster for developing efficient Vertical axis wind turbine farms. The comparison shows that the co-rotating three turbine clusters has higher efficiency than the counter-rotating three turbine cluster. The maximum enhancement in the average power coefficient compared to isolated turbines is 34% for the three co-rotating turbine cluster and 9% for the counter-rotating three turbine cluster. The commercial CFD software FLUENT 14.5 is used for the numerical simulation.
