摘　　要：径向式汽轮机叶轮的叶片角度,叶轮进口直径和叶片宽度等因素直接影响着它的蒸汽利用率和机械效率。针对目前径向式汽轮机效率不高,能量损失偏大等问题,以某径向式汽轮机叶轮为研究对象,利用Proe、Ansys等软件对其进行流体域建模,然后进行网格划分、数值模拟、流场分析等一系列工作,分析了该径向式汽轮机的工作效率和损失,并提出了优化叶轮参数的具体方法。The blade Angle,impeller inlet diameter,blade width and other factors of radial steam turbine directly affect its steam utilization and mechahnical efficiency.Aiming atthe relatively low efficiency and tremendous energy loss of radial turbine,based on a specific radial turbine impeller,this paper usedProe,Ansys software on the fluid domain modeling,meshing,and then make numerical simulation,the flow field analysis and a series of work.Then analyzed the efficiency and loss of this turbine as well as put forward specific solution of impeller parameters optimization.
