This paper reports on void fraction and friction pressure drop measurements made for vertical two-phase flow of air-water across staggered and in-line rod bundles with different pitch-to-diameter ratios. All void fraction data showed a strong mass velocity effect and were significantly less than the values predicted by a homogeneous flow model, but were well correlated using the dimensionless gas velocity, j[sup [asterisk]][sub g]. The two-phase friction multiplier data could be well correlated with the Martinelli parameter for G [gt] 200 kg/m[sup 2]s. The correlations developed for void fraction and two-phase friction multiplier were successfully tested in predicting the total pressure drop in boiling R-113 experiments.
