摘要
提出了一种适合任意风向的新型聚能-遮蔽型立轴风力机,并应用计算流体力学方法,对这种风力机的气动性能进行了数值模拟。研究表明:这种新型立轴风力机比传统的立轴风力机的风能利用率有显著提高。此外,该文还采用了正交优化设计方法,对这种立轴风力机的结构参数进行了优化设计,得到了一组最优的设计参数,该最优设计参数下风力机的风能利用率达37%。
A New-style vertical axis wind turbine with wind collection-shield pattern suitable to arbitrary wind directions was studied using commercial CFD software, the characteristic of this wind turbine was analyzed by numerical simulations. The flow field simulations indicate that the wind energy utilization of this new type wind turbine is much higher than that of the traditional vertical axis wind turbine. Furthermore, the orthogonal optimization of the new-style wind turbine is also conducted for its structure parameters. The wind energy utilization of the best design comes up to 37 %.
