摘要

Experiments have been conducted on the pool boiling of binary mixtures in JK tubes with porous surface and ribbed channels, attempting to enhace the boiling heat transfer coefficients involved. The binary mixtures used in this study are R113 and R11. The results show that the boiling film heat transfer coefficients for the R113 and R11 binary mixtures in JK2 and JK1 tubes are 2-8 times and 2-5 times greater than those in smooth tubes respectively. Based on the this experimental data and simple theoretical analysis, a correlation has been proposed to predict the boiling heat transfer coefficient for R113/R11 mixtures in a horizontal JK tube with a relative error of less than 16/100.
