用强化屏改善低肋管沸腾传热性能的实验研究
摘要
本文针对低肋管沸腾传热的特点
提出加强化屏改善低肋管池沸腾传热性能的方法。对低肋管加强化屏的池沸腾传热进行了实验。实验结果表明
采用强化屏可使低肋管沸腾传热系数提高几倍乃至十倍。强化效果与强化屏的开口度
加热负荷及工质热物性有关。
Abstract
Based on analysis of pool boiling characteristics outside low finned tube
this paper describes a simple method
using enhancing shroud to improve the performance of boiling heat transfer outside the low finned tube. The experiment results show that the boiling heat transfer coefficient can be 7-up to 10-fold enhanced by using shroud. The efficiency of a shroud is related to the size of two windows
heat flux and physical characteristics of test fluids.
