For the liquid in the multi - head twisted and fluted tube can cross the boundary of the channel and merge into the fluid flow in the next channel , the film distribution of multi - head twisted and fluted tube is overmatch single - head twisted and fluted tube 当螺旋槽管表面为多槽道时，各槽道间发生流体的相互掺混使得液膜分布特性较单槽道时要好。
The purpose of this study is to investigate the formation of liquid falling film and its flow behavior on the surface of a horizontal twisted and fluted tube used in the case of wet flue gas desulfurization , desalination , and so on 本文从理论上研究了水平螺旋槽管壁面液膜的形成机理及流动特性，为工业生产过程中高效换热器的应用提供理论基础。本文做的主要工作有： 1
The method was used to analyze the mechanism for enhancing heat transfer by way of using numerical analysis and can be used to study how to apply the field harmony theory to spirally fluted tube strengthen heat - transfer 本文在场协同理论指导下进行了强化换热机理探讨，利用数值分析方法，从分析流场与温度场的协同配合关系入手，研究场协同理论在螺旋槽管强化传热中如何应用问题。
Enhanced heat transfer tube with spiral - surface has simple frame , cheap cost , and wide - ranging purpose . only few dirt can adhere to it and is easy to be washed . it has distinct strengthen effect , and can improve chief heat transfer coefficient at 35 - 40 % comparing with smooth tube exchanger which has same volume and pump power consumption 螺旋型表面强化管结构简单，成本低廉，用途广泛，结垢少且易清洗，其强化效果明显，与体积、消耗泵功率相同的光管式换热器相比，螺旋槽管换热器可以将总传热系数提高35 40 ，因而备受人们青睐。
