Abstract

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 F_tp 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.

Key words: flow boiling, liquid natural gas, two-phase flow, heat transfer

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F_tp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。
