| 中文摘要 | 针对目前国内使用最为广泛的300 MW机组凝汽器,采用具有分布阻力和分布质量汇的多孔介质模型,数值研究了菱型、卵型、将军帽型、双峰型等典型布管凝汽器的性能,比较了不同布管形式凝汽器的壳侧压降和抽气量,总结出了凝汽器布管的一些基本原则,如管束外形以窄长锲型或山峰形为好、外围应设置辅助进汽通道、需要设置渐缩型空冷区等。; The thermal performance of power plant condenser for 300 MW unit,widely used in China,was numerically analyzed using a porous medium model with distributed flow resistance and mass sink.Four typical tube arrangements,lozenge-shaped,egg-shaped,cap-shaped,double-peak-shaped,were considered.The shell side pressure drops and venting rates of condenser for different tube arrangements were compared,and some roles for tube arrangement were concluded,such as,the bundle profile should be wedge-shaped or double-peak-shaped,auxiliary steam inlet sub-channels and the tapered air cooling region should be designed,etc. |
