汽轮机的型线损失占汽轮机总能量损失的1/3以上。为了减少叶型损失，达到节能减排的目的，本文先利用CAD软件画出汽轮机的三种不同叶型的流道内流体的流动区域，然后导入计算流体力学（CFD）软件中的FLUENT模块对流动进行模拟。模拟结果显示，方案一叶型的叶栅内流动状况较好，速度分布比较合理，压力损失较小。方案一叶型明显有较好的气动性能，较小的能量损失。

The loss in turbine's blade is more than 1/3 of the total loss is stream turbine. In order to reduce the loss in turbine's blade, this paper first draw three different blades' flow area by CAD software, then open the pictures in GAMBIT. Meshing them, then simulate in the Computational Fluid Dynamics(CFD). The results show that, the first blade has a better flow condition, distribution of velocity is more reasonable, and lower pressure loss. Thus , the first blade has a better aerodynamic performance, lower energy loss.
