| 中文摘要 | 建立AP1000次级波纹板汽水分离器内两相流动的数学模型,随后数值模拟波纹板内的两相流动,并分析其分离性能。进而对波纹板结构进行优化,得到具有较高分离效率和较低流动阻力的新型波纹板。首先分别建立波纹板内部蒸汽相和液滴相运动的数学模型。然后通过自编程序与Fluent软件耦合对该两相流动模型数值求解。随后得到波纹板进出口总压降,并通过模拟液滴在波纹板内的运动轨迹,得到波纹板的分离效率和内部液滴湿度分布。进而以分离效率和流动压降为目标优化波纹板结构,设计得到具有较高分离效率和较低流动阻力的新型波纹板。本文提出的数值模拟方法对汽水分离器结构的设计和优化具有较强的指导意义。; A mathematical model of two-phase flow was built in the secondary wave-type steam-water separator of AP1000.Then the two-phase flow in wave-type plate was simulated and its separation ability was analyzed.And a new type separator with relatively high separation efficiency and low flow resistance was obtained based on optimizing the structure of the old wave-type plate.Firstly,the mathematical models of steam and droplet phase motion were built in wave-type plate respectively.Secondly,the twophase flow model was solved numerically through our own routine coupled with the software Fluent.Thirdly,the total pressure drop between the inlet and outlet of wave-type plate was calculated.Meanwhile,its separation efficiency and the moisture distributions of droplets were obtained by simulating the droplet trajectories in it.Fourthly,a new type separator with relatively high separation efficiency and low flow resistance was designed after optimizing the structure of the old wave-type plate based on separationefficiency and low pressure drop.Generally,the numerical modeling method in this paper is significantly for designing and optimizing the structure of steam separator. |
