摘　　要：针对Darrieus垂直轴风力透平,本文首先引入多流管方法,并在验证基础上,开展了样机设计和参数化优化研究。结果表明,多流管模型具有较高的准确度。利用此方法获得了Darrieus垂直轴风力透平参数优化的规律性认识。Design and Parameter optimization of a Darrieus type vertical-axis wind turbine （VAWT） is presented. Model of Multiple Streamtubes is adopted in this procedure. After programming, the result of design code is compared with available experiment data. Good estimation can be acquired by this method. Some conclusions have been drawn from parameter optimization. First, power coefficient Cp decreases with increasing the height and aspect ratio of Darrieus type VAWT; maximum efficiency position drift to low velocity ration region as increasing blade solidity, and maximum efficiency decreases, vice versa; maximum efficiency position drift to large velocity ration region as increasing diameter, and maximum efficiency grows up, vice versa. Diameter exerts the most important influence on aerodynamic performance of Darrieus type VAWT.
