Abstract
A numerical model, based on the discrete vortex method, to predict performance and wake of a Savonius wind turbine is discussed, for both stationary and rotating configurations. A detailed parametric study provides fundamental information concerning the starting and dynamic torque time histories, power coefficient, evolution of the wake, Strouhal number, etc. A comparison with the wind tunnel test data showed remarkable correlation suggesting considerable promise for the approach.
