In order to clarify an aerodynamic performance of Magnus wind turbines with spiral fins, wind tunnel experiments and numerical simulations were conducted. The results show that the ratio of lift and drag, L/D, depends on the rotational ratio of η. The maximum L/D of the rotational cylinder with spiral fins was obtained at lower η than that of the cylinder without spiral fins. Therefore, the power for the cylinder rotation can be reduced with the spiral fins. The effective performance was provided at the fins angles around 35 degrees. The simulation results showed the spanwise flow can be observed on the surface of the spiral fins. The power coefficient of the Magnus wind turbines depends on the spanwise velocity on the surface. It revealed that the control of the spanwise flow with spiral fins play an important role in the performance of Magnus wind turbines.
