Abstract

Abstract

The numerical simulation of three dimensional flows in a steam turbine stage with four different curved stators is completed using commercially available CFD code NUMECA in this paper.The characteristics of the flow and the variation of the parameters are analyzed according to the numerical solvers.The efficiency of the stage with four different stators is presented.The results show that the curved stators used in this paper are not to improve the stage efficiency.Lastly,the influence of the curved blade on the horseshoe vortex appearing inside the stator is analyzed.
