摘　　要：对给水泵汽轮机进行了整级的三维粘性流的数值模拟,揭示了该汽轮机存在的气动问题,在第一列动叶栅前缘流场区域会产生激波和普朗特-迈耶波,影响机组的性能.A three-dimensional viscous numerical simulation has been performed for a feed water pump steam turbine. The aerodynamic problem was released in the turbine. The turbine performance was influenced by the shock wave and prandtl-mayer wave in the lead edge flow zone of the first moving blade.
