摘　　要：利用软件模似计算了凝汽器的壳侧流场,并针对凝汽器管束的不同布管方式,分别进行了数值模拟,同时,评判了不同布管方式的优劣。通过计算实例,确定了某型凝汽器管束的设计参数。经分析,定压力评价法的可操作性强,可在工程中实际运用。The flow field of the shell side of condenser is calculated by software simulation, and the numerical simulation is carried out according to the different tube layout of condenser tube bundle, and the advantages and disadvantages of different tube layout are evaluated. Through the calculation example, the design parameters of a type condenser tube bundle are determined. After analysis, the fixed pressure evaluation method is operable and can be applied in engineering.
