| Abstract: | Some related ammonia experiments are reviewed. Thirty-six flow boiling heat transfer correlations are analyzed and evaluated using 1157 R717 experimental data compiled from seven papers. The effect of vapor quality and tube inner diameter on heat transfer coefficients is studied. This paper also compares ammonia's flow boiling heat transfer characteristics with carbon dioxide,nitrogen and water. Several useful conclusions are obtained. The results are helpful for future studies of ammonia flow boiling heat transfer. |
