【摘要】 测量了较大间隙 (τ =0 .0 36 )下常规直叶栅中分面和上下游及栅内的气动参数 ,并与黄洪雁博士测量的较小间隙 (τ=0 .0 2 3)下相同叶栅的试验数据进行了详细比较 ,讨论了间隙尺寸变化对间隙流动和整体叶栅气动特性的影响更多还原

【Abstract】 The airflow parameter in the conventional straight cascade with bigger blade tip clearance(τ=0.036) was measured in detail.The experiment result was compared with that measured by PhD Huang for smaller blade tip clearance(τ=0.023).The effects of tip clearance in clearance flow and blade cascade performance were discussed.更多还原
