摘要

实验研究了竖直微肋管内液化天然气(LNG)流动沸腾传热特性

分析热通量、质量流量以及入口压力对LNG两相流动传热特性的影响。针对实验工况分别采用Kim关联式、Koyama关联式以及两种不同Ftp系数的Wellsandt关联式对传热系数进行预测

并将实验结果与预测结果进行比较。结果表明

在整个实验工况范围内

采用Koyama关联式预测准确性最好。

Abstract

This paper presents an experimental investigation on the heat transfer characteristics of liquid natural gas flow boiling in a vertical microfin tube.The effect of heat flux

inlet pressure and mass flux on the flow boiling heat transfer coefficients was analyzed.The Kim

Koyama

and two kinds of Wellsandt correlations with different Ftp coefficients were used to predict the flow boiling heat transfer coeffi-cients.The predicted results showed that the Koyama correlations were most adaptable under the whole experimental conditions.
