Type of article: Article

Summary

A METHOD FOR PREDICTING THE VARIATION OF NUCLEATE POOL BOILING HEAT TRANSFER COEFFICIENTS WITH COMPOSITION FOR MIXTURES IS PRESENTED. THE RISE IN THE LOCAL BOILING POINT OF THE LIQUID, T, ADJACENT TO THE HEATED SURFACE CAUSED BY PREFERENTIAL EVAPORATION OF THE VOLATILE COMPONENT HAS A LIMIT AT THE PEAK NUCLEATE HEAT FLUX. T CAN BE DETERMINED FROM KNOWLEDGE OF ONLY THE PHASE EQUILIBRIUM DIAGRAM AT THE PRESSURE OF INTEREST. THE EQUATION INCORPORATING T ACCURATELY PREDICTS PUBLISHED EXPERIMENTAL BOILING HEAT TRANSFER COEFFICIENTS AT HEAT FLUXES WELL BELOW THE PEAK FLUX FOR THE BINARY MIXTURES: ETHANOL-WATER, ACETONE-WATER, ETHANOL-BENZENE, NITROGEN-ARGON, NITROGEN-OXYGEN, AND NITROGEN-METHANE.
