✦ Synopsis

Void fraction and friction pressure drop measurements are made for an adiabatic vertical up-and-down two-phase flow of air-water mixture across a horizontal, in-line, 5 × 20 tube bundle with a pitch-to-diameter ratio of 1.28. The average void fraction and friction pressure drop show a strong mass velocity effect; the data of void fraction are significantly lower than those predicted by a homogeneous flow model. New correlations for predicting void fraction and two-phase pressure drop in vertical up-and-down flow across a horizontal tube bundle are presented. The data are compared to those of previously published literatures.
