Experiments were carried out to determine the influence of fluid flow and liquid subcooling on flow boiling heat transfer of Freon-113 across horizontal tubes. The data cover wide ranges of velocity (1.5 to 6.9 m/s) and extremely high levels of liquid subcooling (29 to 100°C) at pressures ranging from 122 to 509 kPa. Thin-walled cylindrical electric resistance heaters made of Hastelloy-C with diameter of 6.35 mm were used. The azimuthal wall temperature distributions were measured with five thermocouples around the heaters. The data were compared with Chen’s two-mechanism model with modification for subcooled flow boiling. A new nucleate boiling suppression factor for cross flow was developed. The improved model could predict the present data and Yilmaz and Westwater’s (1980) data well with a mean error ratio of 1.02 and standard deviation of 0.17.
