摘要
本文利用FLUENT UDF对水平轴风力机叶片翼型霜冰结冰的情况进行了数值模拟,得到不同环境参数下,叶片翼型霜冰结冰的特性。对结冰翼型气动性能的分析结果表明,叶片结冰后,最大升阻比下降了36.7%,严重降低气动性能,在严重降低风力机性能的同时,对叶片本身安全造成影响。
FLUENT UDF was used to investigate the rime icing of the blade airfoil of the horizontal axis wind turbine .The characteristic of rime icing on blade airfoil was obtained in the condition of the different environmental parameters .The results of analyzing on iced airfoils showed that the ice accretion would depress the aerodynamic performance of the airfoil , and the maximum ratio of lift to drag decreased by 36 .7%.It would reduce the performance of the wind turbine , while it would make the serious influence on the safety of the blade .
