Numerical Simulation on Static Performance of Savonius Rotor Based on Different Turbulence Models

Abstract:

With the advance of computer technology, numerical simulations were widely used for designing wind turbine. Savonius rotor is a kind of drag type wind turbine often used for water pumping for its good torque performance. In this study, numerical computations were carried out based on three different turbulence models including Splart-Allaras (S-A) model, k-εmodel and k- ωmodel to compute the static torque performance at different attack angles. Flow fields around the Savonius rotor were obtained. Comparing the computation results with the experimental results, the effects of turbulence models on the static performances of the Savonius rotor were discussed. The simulation result based on k-ω model was in agreement with test data generally.
