摘要
在垂直轴风力机结构设计的基础之上,采用CFD技术对其流场及气动性能作了深入分析。根据分析结果来研究叶尖速比、叶片翼型、叶片安装角度等因素对风力机气动性能的影响,得出了翼型在叶尖速比λ=2、风速约为12 m/s时,风力机风能利用率最大,从而为风机叶轮优化设计提供了参考。
Based on the designed vertical axis wind turbine,the CFD technique was used to analyze the flow field and aerodynamic performance.According to the analysis results,the influence of the tip speed ratio,blade,blade angle and other factors on aerodynamic performance of wind turbine was studied.It is obtained that the wind energy utilization rate is maximum with tip speed ratioλ=2,wind speed is about 12 m/s.It provides reference for the optimization design of fan impeller.
