摘　　要：利用Fluent软件采用标准k-ε湍流模型和SIMPLE算法,对不同重叠比下S型垂直轴风力机进行二维数值模拟研究,发现在相同风轮迎风尺寸的情况下重叠比为0.50时风力机的性能最佳,相应的最大功率系数为0.261。The two-dimension numerical simulation of Savonius rotors with different overlap ratios was carried out using computational fluid dynamics software Fluent. The results indicated that when the rotor area stays the same, there are the best performances for wind turbine with an overlap ratio of 0. 5, and the corresponding maximum power coefficient is 0. 261.
