Title: Prediction of the Mixture Effect On Boiling in Vertical Thermosyphon Reboilers
Abstract: Abstract The present study has investigated the effect of mixtures on the nucleate boiling contribution to flow boiling inside vertical tubes at low vapor qualities, operating conditions typical of vertical thermosyphon reboilers. The mass diffusion process created by the composition difference between the vapor and liquid phases was found to impede the boiling process and substantially reduce the nucleate boiling heat transfer contribution to flow boiling in mixtures. Two widely quoted flow boiling mixture correction factors were tested against a published set of experimental data for ethanol/cyclohexane mixtures and were determined to be only partially reliable. Instead, several theoretically based nucleate pool boiling mixture correlations were shown to be accurate for flow boiling conditions and are recommended for design use.
