Title: A numerical comparison study between co-rotating and counter-rotating savonius wind turbine clusters
Shaaban Abdallah, a professor of Aerospace Engineering, has been at the university of Cincinnati since 1989. He obtained his PhD in Aerospace Engineering at the University of Cincinnati in 1980. Dr. Abdallah joined Penn State University from 1981 to 1988. His research interests include Computational Fluid Dynamics, nano fluids, Turbo-machines, Unmanned Aerial Vehicles and Medical devices. Abdallah has two US patents on centrifugal compressors and three disclosures with university of Cincinnati on medical devices.
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.
