摘要: 为获得相对平稳且非负的启动力矩,针对三叶片Savonius风力机开展研究。首先对比研究两叶片和三叶片Savonius风力机的启动性能和输出功率特性。在此基础上,针对其主要的结构参数重叠比开展研究。针对三叶片的结构特点,提出重叠比和净重叠比的定义方式,设置9组不同净重叠比,范围在0~0.36(重叠比范围0.14~0.50)之间。利用数值模拟和风洞试验相结合的方法,研究在不同风速下重叠比对Savonius风力机启动力矩以及输出功率性能的影响。结果表明:净重叠比可消除反向启动力矩,并提升三叶片Savonius风力机的启动性能,平均启动力矩系数最高提升147.06%。净重叠比在0.06~0.11范围内时,对风力机的输出功率有提高作用。

Abstract: Three-bladed Savonius wind turbines are investigated in this paper in order to obtain a relatively smooth and non-negative starting torque. The starting ability and output power characteristics of two-bladed and three-bladed Savonius wind turbines are compared firstly, and the overlap ratio is studied as one of the important structural parameters. The overlap ratio and net overlap ratio of the three-blade Savonius wind turbine are defined according to its structural characteristics. Nine groups of different net overlap ratios are set, ranging from 0 to 0.36 (overlap ratio range from 0.14 to 0.50). The effect of overlap ratio on the starting torque and output power performance of the Savonius wind turbine at different wind speeds are investigated by using numerical simulations and wind tunnel tests. The results show that the reverse starting torque can be eliminated and the starting performance can be improved by setting the net overlap ratio, with a 147.06% maximum increase of average starting torque factor. The output power of wind turbine can be improved when the net overlap ratio is in the range of 0.06-0.11.

Key words: wind turbines, wind tunnels, numerical simulation, overlap ratio, starting performance
