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.

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