摘　　要：蒸汽汽轮机叶栅内流动属于变截面管流问题。本文利用力学知识建立了叶栅机翼理论,利用Computational Fluid Dynamics(CFD)软件对蒸汽在汽轮机叶栅内的流动进行了数值模拟研究,包括稳态流动及非稳态流动,并对叶栅内部蒸汽流动的压力和马赫数进行了动态显示,分析研究验证了与流体力学有关机翼和叶栅边界层理论知识。The flow in the steam turbine cascades is tapered pipe flow problem. The cascade airfoil theory has been established by using the knowledge of mechanics,and steam flow in turbine cascade was numerical simulation studied by using Computational Fluid Dynamics （CFD） software. The research topic includes the steady flow and unsteady flow. The pressure and Maher number of the internal steam cascade flow were dynamic displayed. The research of wing and blade boundary layer theory about fluid mechanics was analyzed and verified.
