摘要: 通过三维欧拉非定常流场与弹性叶片动态响应的迭代计算,研究汽轮机叶片—流场系统的稳定性及其动态特性。对某一蒸汽轮机动叶片排,有一定的流量范围内,根据各自工况下静叶出口的不均匀流场,求得动叶片—流场系统的动态特性,判别其运行的稳定性范围。

Abstract: Through iterational calculation of three-dimensional Euler unsteady flow-field and steam turbine blade dynamic response,the stability of blade and flow-field is studied. The dynamic characteristic of blade and flow-field is obtained for a stage of steam turbine in a large operating range. And it can be used to estimate the stability or stable working range for turbomachinery.

Key words: Interation, Oscillating blade, Stability, Steam turbine, Wake
