✦ Synopsis

Pool boiling data were obtained for toluene, carbon tetrachloride, methanol, N-propanol, isopropanol, water and water-isopropanol azeotrope at atmospheric pressure using a wire with a stable surface for all the experimental data reported here. The wire 0.0315 cm dia., was a nickel-aluminium alloy. Its surface was stabilised by an annealing process and prolonged boiling. The results for these seven liquids were correlated by the following modified equation of Borishanskii and Minchenko:

Nu = EPe""K,o'7[ T,/TJ4

where the constant E = 6.30 X 10m4. Boiling data of Cichelli and Bonilla for ethanol, N-heptane and benzene, for a range of pressures 05-52 atm., obtained on a clean chromium plated copper surface were correlated by the same equation with the constant E = 3.92 x 10-4.

The experimental data of Borishanskii et al. for water at pressures ranging from 1.0 to 74.5 atm. obtained on a stainless steel surface are correlated by this equation with E = 8.9 x lo+.

These results indicate that in the "liquid-surface combination factor" the properties of the heat transfer surface constitute the dominating part.
