摘　　要：利用七孔探针流场测试技术,分别对有侧滑角和无侧滑角风机缩比模型的尾流区进行测量,得到尾流效应影响区的测试结果,以及侧滑角对尾流的偏转影响。给尾流数值模拟提供数据参考,并为风场布机方案研究提供技术支持。The research of the wake of wind turbine, being applied to the wind field arrangement, could effectively control the prediction error of annual electricity yield. Using seven-hole probe 3D flow-field test system, wakes of the models with sideslip angle and zero sideslip angle were measured, respectively, and the testing results of wake effect area and the effect of sideslip angle on deflection of wake were achieved. The numerical simulation of wake provided the reference data and the technical suDoort for wind filed research.
