| 中文摘要: |
| 基于(势流)涡尾迹方法开发了水平轴风力机叶片气动性能分析程序,采用固定尾迹涡模型和自由尾迹模型分别对气动设计性能进行计算分析,得到风力机设计工况下的涡位置、诱导因子、功率系数及扭矩系数等气动性能参数,并与设计结果对比。结果表明,涡尾迹方法能够快速准确地计算风力机叶片气动性能参数,对风力机叶片气动分析,固定尾迹涡模型较自由尾迹模型计算时间短,具有较好的实用性。 |
| 英文摘要: |
| This paper developed a design and analysis procedure for rotor blades,based on vortex methods.This procedure is applied to calculate the vortex location,thrust coefficient,power coefficient and induced velocity distribution in different conditions,used fixed pitch model and free wake model to optimize the design of the aerodynamic analysis.The results show that vortex methods are able to calculate aerodynamic performance parameters quickly and accurately.The fix pitch model can greatly reduce the time of the early design of wind turbine blades. |
