摘要
采用数值模拟技术详细地研究了不同掠高的某蒸汽轮机末级叶片前掠正交设计对叶栅总体参数的影响。计算结果表明,在进行正交性设计时,掠高应选在25%相对叶高左右。
In this paper, the numerical simulation technique is used to investigating the effect of different swept depth of a turbine last stage blades with forward swept orthogonal design on the entirety parameters of the cascades. The results show that for orthogonal designing schemes, the swept depth will be about 25% of the relative blade height.
