摘　　要：采用数值方法对１台３２８ＭＷ汽轮机凝汽器壳侧的流动与传热进行了计算。根据对计算结果的分析，提出了改善凝汽器工作特性的管束改造方案。数值预测结果证实所建议方案的合理性。Abstract The shell side and heat transfer of a 328MW steam turbine condenser are calculated numerically. With the analysis of the calculation results, suggestions of remodeling tube arrangement are proposed to improve the performance of the condenser. Numerical predictions show that good results can be achieved by adopting these suggestions.
