摘要：As the second report on the same subject, the shielding effects of wind among wind turbines deployed in a wind farm are further investigated. In the first report 1) , the shielding effects among wind turbines were investigated by varying the spacing and the wind direction systematically. In this second report, models of different scale (two times the size of the models used in the first report) are used in order to examine the scale effect, especially the effect of Reynolds number. The effects of the power coefficient of wind turbines on the shielding effects are also investigated.As in the study reported in the first report, the experiments are conducted while using circular disks with holes, which are not geometrically similar to real wind turbines. Besides, the experiments are conducted in a wave tank instead of in a wind tunnel. The justifications of these ambiguities are examined in this study by comparing with other existing experimental results and also by comparing with the results of CFD (Computational Fluid Dynamics) calculations..
