  • To reduce the stator profile loss and improve the efficiency of the industrial steam turbine,a numerical analysis and optimization of the data for the steam turbine stator blade are conducted by the NUMECA,a CFD software.The result shows that,compared with the original blade,the "after loading" blade is with the best static pressure coefficient distribution,and effectively postpones the transition point position,reduces the radial pressure gradient of suction surface,and cut down the secondary flow loss effectively.The total pressure losses of the "after loading" blade is 1.03%,which is the least,and the single-stage efficiency is 94.462%,which is the maximum and increases 14.33%.Thus,the aerodynamic performance of stage is im-proved obviously,the profile loss decreases through using the "after loading" blade.
