摘　　要：采用滑移网格技术对不同参数下的小型垂直轴叶轮瞬态流场进行了数值计算,着重研究了不同安装角、翼型、叶片弦长、叶片数对叶轮功率的影响,得出不同转速下使叶轮获得最大功率的最佳翼型、叶片安装角、弦长和叶片数,并通过吹风实验验证了最佳叶片数和最佳弦长时的垂直轴风力机具有较优的气动性能。Numerical simulation on unsteady rotated flow of vertical axis wind turbine with different parameters is done based on moving meshes, and it＇s mainly studied that power of vertical axis wind turbine is affected by different installation angles, airfoils, chord lengths, number of blades. It is proved that when the blade installation Angle , the chord length , the number of blade , and airfoil are best, vertical axis wind turbine can obtain maximum power. At last, the optimal number of blades and chord lengths are testified in the further blowing experiments, and now the optimal aerodynamic performance of vertical axis wind turbine is gotten.
