应用流体旋转法的多种强化传热方式

some heat transfer modes of using fluid rotary method to strengthen heat transfer

概述了应用流体旋转法强化管内单相流的几种强化传热方式及强化传热的机理 ;并利用分析 ,从经济用能方面比较了这几种强化传热方式 ,得出椭圆断面厚壁螺旋管在损失率最小的情况下 ,其流动工况较高 ,达到了强化传热的目的。

Summarize some heat transfer modes of using fluid rotary method to strengthen single-phase fluid in tube、heat transfer mechanism and use the entropy analysis,compare these kinds strengthen way of heat transfer from economic using energy,bring forth oval cross section and heavy wall spiral tubes flow regime Reopt is high at its least entropy loss rate , achieve the goal of heat transfer enhance ment.
