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
