采用离散涡方法数值仿真了不同来流攻角下，固定与动边界叶栅绕流。在设计工况时流动接近定常流动。
The unsteady flow past stationary and oscillating cascade for off-design performance respectively are simulated numerically with the Discrete Vortex Method.
优化了300MW汽轮机的调节级，采用了子午面端壁收缩的弯曲叶栅，动叶为自带围带三销钉三联叶片，再用铆接围带形成整圈联结叶片。
The control stage of improved 300MW steam turbine used bowed static blade cascades with convergent tip endwall and integral shroud triple pin rotating blades.
