摘　　要：使用商业软件NUMECA,对某汽轮机调节级全周进汽下的流场进行数值模拟,发现整体轴向力为负值,作者对这一对其气动性能现象进行深入分析研究。考虑到部分进汽时机组的稳定性,对部分进汽下的流场进行数值模拟,分析部分进汽调节级内部流动的非定常现象,并着重分析部分进汽对下游两列动叶栅轴向力的影响,并与全进汽下的轴向力对比。When simulated the flow field of the Control Stage under full arc admission, found that the axial-thrust is negative, then researched deeper. Considering the steady of turbine under partial admission, simulated the flow field of control stage under partial admission and study the unsteady phenomena. Then analyzed the influence to axial force of down steam two cascades at the result of partial admission and compared with the result under full admission.
