摘　　要：针对传统的立轴风力机风能利用率低的问题,应用正交优化法和流场数值模拟技术对聚风导流型立轴风力机的结构设计参数进行了优化设计。在同尺度下与传统立轴风力机进行了对比分析。结果表明,聚风导流型立轴风力机叶轮的输出功率、风能利用率及自启动特性均得到了显著提高。Aiming at low wind energy utilization factor of traditional vertical axis wind turbine,orthogonal optimization and numerical simulation of flow field are applied to design structure parameters of the vertical axis wind turbine with wind collection-guided pattern.And then a set of optimal design parameters are obtained.Compared with the traditional vertical axis wind turbine under the same conditions,the results show that it obviously improves output power,wind energy utilization factor and start-up characteristics of the vertical axis wind turbine with wind collection-guided pattern.
