The verification of the three-dimensional one-way bubble tracking method (BTM) proposed in our previous report is carried out through the comparisons between measured and predicted developing bubble-slug flows in a vertical pipe. The approaching process of two large bubbles in various liquid flow conditions is well predicted by a wake field model implemented in BTM. Good predictions are also obtained for the spatial evolutions of flow patterns, mean void fractions, void fluctuations, radial
