Description
The formulation of the interfacial area transport (IAT) equation is based on statistical mechanics and its concept has been fully established (Ishii, 2006). However, the source and the sink terms of interfacial area due to bubble coalescence and breakup are still being developed. These are strongly dependent on flow conditions and geometries. So far, most experiments for interfacial area research have been performed in round tubes. There is very few data for the flow in an annulus. Hibiki et al. (2003) performed experiments in an annular channel, but their flow conditions were limited to bubbly flows. In this paper, an experimental study has been performed to investigate the interfacial area transport of vertical upward air-water two-phase flow in an annulus channel for a wide range of flow conditions
