An analysis is presented on the problems existing in the flow passage of N100-90/535 steam turbine operating for several years, then the detailed treatment methods are proposed, and an assessment and evaluation is conducted for the operation effects after the retrofit.

Various measures for moisture removing and erosion proof measures for the flow passage of large steam turbine were presented in details.

After improving the design of the last stage s flow passage of 18MW steam turbine made by Nanjing Turbine and Electric Machinery Ltd.

In the design of a low bypass ratio fan stage,this paper links the through flow inverse problem of the fan rotor,the core channel fan stator and the bypass channel fan stator together,as an organic whole,with the splitter aerodynamic design problem.
