【摘要】 本文在不同雷诺数下对两套环形叶栅的出口流场进行了详细测量，得到了雷诺数与叶栅性能参数的关系曲线。实验结果表明，雷诺数是影响叶栅性能的一个很重要的参数。更多还原

【Abstract】 Under differnt Reynolds numbers two sets of annular cascade outlet flow fieds were measured in detail and the relation curves of Reynolds number and cascade loss obtained. The experimental results show that the Reynolds number can signifcantly affect, the cascade performance.更多还原
