摘要
通过吹风实验,探讨了在不同径高比和外壁面扩张角的汽轮机环形静叶栅中叶片倾斜对叶栅出口流场的影响.实验结果表明:采用最佳倾斜角叶片能降低叶栅能量损失和改善叶栅出口流场的气动性能.
With the help of wind tunnel tests, the effect of blade inclination on cascade outlet flow fields in static annular turbine cascades with different diameter-blade height ratios and different outer wall divergence is discussed. Experimental results show that by using an optimal angle of inclination energy losses can be reduced and outlet flow fields improved. 9 figs and 10 refs.
