This study was conducted based on the idea that the closely spaced Savonius wind turbines located along the side of a road may also work as a wind shield. Wind tunnel experiments were conducted to clarify the wind speed reduction in the wake of the closely spaced three turbines and the power generation characteristics. Closely spaced turbines such as the center to center distance of 1.5 times of the turbine diameter had good shielding effects; also the turbines with the same rotational direction had better shielding than that with the alternate rotational direction. When the turbines were fixed not to rotate, the shielding effects differed very much depending on the position of the buckets. About the power coefficients, three turbines in the same rotational direction seemed to have slightly higher value than the alternate rotational direction and single turbine cases, but further study is necessary to confirm the results.
