摘　　要：气流横向冲刷圆壳管束换热广泛应用于各种工程实际中,通过对这种形式的换热进行试验研究以及与横向冲刷均匀管束换热进行对比,分析了进口扩张角对传热和阻力性能的影响。研究结果可为工程应用提供参考。Air flow across the tube bundles in cylindrical shell in heat exchanger is popular in many industries, but the report is few in this research fields. The experimental research on heat transfer properties of gas flow across the bundle tubes in cylindrical shell was carried out. The properties of heat transfer are compared with equal velocity inflow and different expand angles inflow. The influence of inlet expand angle on heat transfer is analysed. The results are proposed for practical application.
