| 摘 要： | Savonius风机是一种典型的垂直轴风力发电机,通过对其进行流固耦合分析,研究叶片转角对风机气动性能的影响。利用ANSYS的CFX流体模块,流体湍流模型选择基于RANS的标准k-ε湍流模型,对风轮进行流固耦合分析,从而获得叶片产生的力矩情况,并计算了风机的功率特性。利用求解结果,得到了力矩系数与叶片转角之间的关系。分析了风机叶片在旋转一周中所产生的最大扭矩以及负扭矩所处的位置和范围。通过分析转角对风机性能的影响,可为今后的Savonius风机叶片形状优化和效率提升提供参考。

| Abstract: | Savonius rotor is a typical style of vertical-axis wind turbine(VAWT).The study on the aerodynamic performance of small Savonius wind turbine influenced by blade angle was presented in the paper.Fluid-solid coupling analysis on the Savonius rotor was carried out based on ANSYS CFX.And the standard kε turbulence model was used in the simulation analysis of savonius rotor.The power characteristics were calculated after getting the data about torque and velocity distribution by numerical simulation.And then the relation between torque coefficient and blade angle was obtained by using the analysis results.According to analysis results,got the point and the range that generating the maximum torque and the negative torque.And it can offer a useful reference for the further study on Savonius wind turbine in the future by the analysis of blade angle’s influence on the turbine characters. |
