Abstract

The present series of experiments were undertaken in order to provide additional information on the effects of different heating surface materials on boiling heat transfer. Three different materials were used in conjunction with three different fluids.

Wires of platinum, tungsten and iron were chosen for the heating surface materials. All wires were approximately 0.010 inches in diameter and two inches long. The fluids used were methyl alcohol, carbon tetrachloride and iso-octane. Measurements of wire temperature and heat flux were made with the wire immersed in the fluid and heated electrically.

The results indicated that there was no major effect of the heating surface material on either the burnout heat flux or on the temperature of the nucleate boiling region. These findings are, of course, limited to the wire-fluid combinations tested as well as to the range of experimental conditions investigated.
