Abstract: Experiments were made on fluid flow resistance and heat transfer in theshell side of tubular heat exchangers with longitudinal flow, and the performance of heat transfer enhancement of transversally fluted tube bundle supported with the ROD tube supports was compared with that of the same tube bundle but supported with the RING tube supports. The results showed that roughness tube bundle supported with RING tube supports had better performance of heat transfer. In this paper the measurements of fluid velocity distribution made with LDV within roughness tube bundles and in the downstream direction of tube supports are given, and the influence of the forms of tube supports on heat transfer performance of tube bundles is analysed.

摘要： 通过对壳程流体纵向冲刷型管壳式换热器的传热与流体阻力实验,比较了横纹槽管管束在折流杆支撑和空心环支撑两种情况下的传热强化特性,发现空心环管间支撑物比拆流杯管间支撑物有较好的性能.此外,还报道了用激光测速测量壳程流体在管间支撑物条件下的流速分布,分析了管间支撑物结构对传热性能的影响.
