| Abstract: | 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. |
