【摘要】 排汽管道布置形式和内部结构是直接空冷排汽系统优化设计的基础,直接影响各蒸汽分配管内的流动阻力和流量分配。利用计算流体动力学软件(CFD),对某660MW超临界直接空冷机组排汽管道内的水蒸汽流场进行了数值模拟。通过对三维排汽管道内水蒸汽流场的模拟、分析和研究,为直接空冷排汽管道系统的优化设计提供帮助。更多还原

【Abstract】 The optimal design for exhaust ducting mode and internal structure in direct cooling exhaust duct system is very important for us.It’s influencing every steam to assign the flow obstruction and flow while managing to assign directly.The flowing field of steam in direct air cooling exhaust duct for a certain 660MW power generating unit is simulated via computational fluid dynamics(CFD) software called fluent.The simulating results for steam in 3-dimensional duct are analyzed and studied.It offers good help for the optimal design of air cooling exhaust duct system.更多还原
