大焓降后部加载弯叶栅压力场与壁面流场特性的实验研究

Experimental investigation on pressure field and surface flow field characteristics of large enthalpy drop aft-loading curved turbine cascade

  • 摘要: 在环形叶栅低速风洞中,对亚临界600MW汽轮机中间级大焓降静叶栅进行了吹风实验.应用五孔球头测针,详细测量了在3个冲角下叶片沿叶高和节距的气流参数分布;借助沿叶型的静压测孔测量了在9个相对叶高位置沿叶型的静压系数;并应用墨迹显示技术,显示了沿上、下端壁及叶片表面的极限流线.实验结果表明,大焓降静叶栅具有良好的气动性能.
