摘　　要：以某硫酸厂大型管壳式乙二醇换热器为分析对象,采用CFD软件FLUENT对其整体结构进行数值模拟,得出了换热器整体流场和温度场特性,分析了关键区域折流板和特征换热管的温度分布,并与实际测量值作出对比。研究结果可为换热器的设计方法和换热器的故障分析手段提供参考。The computation fluid dynamics（ CFD） was used to predict the flow field and temperature field inside the shell and tube heat exchanger of a vitriol plant. The temperature distribution of the key regional baffle plates and heat exchange tube were analyzed. The CFD model was established and calculated with Fluent software. The results of the research can offer reference to the design and improvement of the shell and tube heat exchanger.
