摘要

对环形通道内低Pe数(20～70)的高温(300～700℃)液钠在由非旺盛湍流转变成旺盛湍流区内(Re=4000～17500)的传热进行了实验研究

并对正压下液钠初始沸腾壁面过热度进行了理论分析与实验研究.结果表明

所提供的计算关系式与实验数据吻合良好.实验采用的环管内径为6mm

外径为10mm

通道外壁绝热

内壁用高热流密度电加热元件加热.

Abstract

This paper deals with the experimental research of heat tranafer to liquid sodium with low Pe and high temperature and its incipient boiling wall superheat under a positive pressure in an annulus. The experimental research and theoretical analysis show the semi-empirical correlations obtained coincide with the experimental data very well. In the experiments the inner diameter of the annulus is 6mm and the outer diameter is 10mm The inner wall is heated by electrically heating element

and the outer wall is heat-insulated.
