Analysis of matching characteristic of transonic tandem stator airfoil and its optimization

  • 摘要: 以数值模拟的方法对串列叶片的匹配特性展开研究,分析其前后排叶片的工作特点,并在此基础上利用可控扩散叶型(CDA叶型)替换常规叶型,有效提高了叶栅性能.研究结果表明:随来流攻角的变化,前排叶片的工作状态变化很大,并且串列叶栅的可用攻角范围几乎只由前排叶片决定;而后排叶片的攻角由前排叶片落后角确定,同时前排叶片的尾迹在后排主流区中的堆积能够削弱后排叶片中气流扩压的过程,前排分离严重的情况下,后排叶片工作状态反而有所改善.在分析串列叶片工作特点的基础上,以CDA叶型分别替换常规叶型能够取得良好的效果.
