摘要：

浓缩风能型风力发电机的流场具有特殊性,它的流场特性直接影响该类型风力发电机的性能。浓缩风能的目的是为了有效地提高风能品位、单机输出功率和风能资源利用率,降低风电度电成本。200W浓缩风能型风力发电机是由风洞测试后的浓缩风能型风力发电机整体试验模型简化改进的实用机型。采用车载法对200W浓缩风能型风力发电机相似模型的流场进行了测试,运用皮托管和数字压力计测试了各断面特征点的总压、静压,获取了流场流速分布等特性。试验表明:相似模型的中央圆筒叶轮安装处流速增至来流流速的1.31倍,风能增至来流风能的2.25倍。通过相似模型的车载法试验结果分析研究,找出了流场流速分布的规律性。

摘要：

Due to the unique characteristics of the flow field of concentrated wind energy turbine,its characteristics of the flow field influence the performance of the concentrated wind energy turbine directly.Concentrating wind energy is in the purpose of using wind resource efficiently,raising the quality of the wind energy,increasing the output power and reducing the cost of per kilowatt.The 200 W concentrated wind energy turbine is the practical type that is converted from a model that had been tested in wind tunnel.The flow field of resembled model of 200 W concentrated wind energy turbine was tested outside in truck and the static pressure and total pressure of special point in each section was tested by Pitot and Digital pressure gauge,and the distribution of flow speed in the field was obtained.The test results show that it is 1.31 times faster than natural speed of wind where(impeller) installed in middle of the cylinder in the resembled model and the wind energy increases to 2.25 times of the natural wind flow.Through the analysis of the result of resembled model that was tested outside in truck,the regulation on speed distribution was found.
