摘要
针对将AP1000核主泵转速从1 750 r/min降低到1 450 r/min,应用强制漩涡法和速度系数法设计核主泵叶轮和环形压水室,设计出扭曲叶片和扩散叶片两种结构形式的导叶。利用Fluent软件,对不同导叶设计工况进行数值模拟,对主泵内部静压分布和流线分布进行分析,较好地揭示了过流部件内部流动的主要特征。
As we know AP1000 nuclear power plant adopts the reactor coolant pump with rotational speed of 1 450 r/min,different from conventional 1 750 r/min.Using forced vortex method and velocity modulus method,relevant components of the reactor coolant pump were designed,including the impeller,annulus water chamber,twist and diffusion 2 types of guide vanes etc.Numerical simulation on different design conditions of the guide vane was carried out based on Fluent software,while static pressure distribution and flow pattern inside the coolant pump analyzed,showing the actual flow field characteristics inside the pump.
