摘要
利用计算流体力学软件FLUENT,对大同600 MW发电机组直接空冷三维排汽管道内的水蒸汽流场进行了数值模拟.结果显示:流经各蒸汽分配管的水蒸汽压降不同,流量分配不均.研究结果为直接空冷排汽管道系统结构的优化设计提供帮助.
The three dimensional flowing field of steam in direct air cooling exhaust ducts was simulated via computational fluid dynamics （CFD） software called fluent for Datong 600MW power generating unit. Results show that the pressure drops of the steam flowing through distribution manifolds are not the same, so as the mass flow. The studying results can provide assistance for the system structure＇s optimal design of direct air cooling exhaust ducts. Figs. 3, table 3 and refs. 3.
