摘　　要：针对纵剖式离心压缩机中间冷却器壳程污垢沉积并产生垢下腐蚀的问题,应用计算流体力学(CFD)的FLUENT软件,建立中间冷却器内部流场的三维流动数学模型,分析其内部流场分布和流动状态并将结果与Halle等的实验结果进行比较,认为中间冷却器壳程循环水流场分布不均是产生污垢沉积和垢下腐蚀的原因。据此对中间冷却器壳程结构进行了改进,使其使用寿命提高到2 a以上。In view of the difference between shell and stream compact heat exchangers and the world＇s most advanced products in several crucial technical indexes like operational life that affects the normal operation of the equipment,fundamental principles of fluid mechanics.Computational fluid dynamics（CFD） and FLUENT numerical were used to simulate shell and stream compact heat exchangers＇ variation regularities of non-stationary flow field.Quantitatively analyzing on crucial technical indexes of the long-term running and operational life of equipment has provided an important basis for reliability design and proper running of equipment.
