Numercial Simulation on Three-Dimensional Unsteady Flow in a Supercharged Boiler Gas Turbine

摘要：

　　To the unsteady characteristic of three-dimensional flow in the gas turbine blade cascades,based on sliding mesh and a standard k-ε turbulent flow model,Fluent software was employed to solve the Reynolds averaged N-S equation.The numberical result of unsteady flow field is obtained in gas turbine cascade for supercharged marine boiler.This paper shows the axial distribution of Ma in the position of β=0 in a calculational period time,and the effect of trails to flow field characteristics.The result can provide guidelines for aerodynamic optimization design of gas turbine stage cascade.
