Abstract

Results are reported of an experimental study of heat transfer in pool boiling of dilute emulsions of pentane in water and FC-72 in water. Heat transfer data for single phase convection, boiling of the dispersed component, and enhanced boiling of the continuous component are correlated with images of the emulsion near the heated surface. Large bubbles are observed to form on the heated surface and remain attached to the surface. There is evidence of boiling of individual droplets that do not contact the heated surface under some circumstances. For very dilute emulsions and at moderate heat flux the attached bubbles are the dominant boiling mode.
