摘要

在以前对闭式循环系统中螺旋管蒸发器内汽液两相流压力降脉动进行系统实验研究、根据脉动过程特征和产生原因进行分析、区分了产生压力降脉动的两类不同特征区域的基础上

着重对第二区压力降脉动流动过程中瞬态及时均传热的特征和规律进行了试验与分析研究

总结出相应的规律和计算式 .

Abstract

On the basis of the classification and definitions of two regions of pressure drop oscillation in our previous work

the transient and time-averaged heat transfer characteristics of steam-water two-phase flow during the second regional pressure drop oscillation were experimentally studied in a closed circulation system with a helical coiled tube boiling channel. New non-dimensional parameters and criterion for characterizing the effects of second regional pressure drop oscillation on transient and time-averaged heat transfer coefficient were proposed.
