An experimental study of pool boiling was conducted, using cylindrical heater surfaces of platinum, silicon dioxide, and aluminum oxide. They were immersed in FC-72 and R-113, saturated at 1-atm pressure. The effects of fluid and surface material on boiling incipience and on the nucleate boiling curve were investigated. A probabilistic representation was used to present the incipience wall superheat values, which scattered widely for ostensibly identical runs. The difference in incipience wall superheat values between those with FC-72 and R-113 was significant, but the surface material effect on boiling incipience was small. The surface material effect was more pronounced in the nucleate boiling regime than on the incipience process.
