The purpose of this study is to investigate the two-phase flow in a kettle reboiler in order to improve the design methods used for them. An air-water in-line tube bundle was designed and constructed with tubes 38 mm in outside diameter on a pitch to diameter ratio of 1.32 to provide two phase pressure drop data. These data and other data from the literature were used to investigate the two-fluid model proposed by Simovic et al. [1] and the conventional 1-D design model, implemented with three separate void fraction correlations and one two-phase friction multiplier correlation. The results showed that the two-fluid model predicted air-water void fraction data well but R113 data poorly, with pressure drop predictions for both being unsatisfactory. The one-dimensional model was shown to predict pressure-drop and void fraction data reasonably well, provided the Feenstra et al. [2] correlation for void fraction and the Ishihara et al. [3] correlation for two-phase friction multiplier were used.
