Interactions between gas-liquid mass transfer and bubble behaviours.

ABSTRACT: Interactions between gas-liquid mass transfer and bubble behaviours were investigated to improve the understanding of the relationship between the two sides. The CO₂/N₂-water system was applied to study the bubble behaviours based on the volume-of-fluid (VOF) model. The mass transfer conditions were taken into consideration when the fluid field was analysed. The bubble behaviours were compared with and without mass transfer. The results show that the absolute slopes of the curves for mass fraction inside the single rising bubbles, with diameters from 3 to 6 mm, decrease from 0.09325 to 0.02818. It means that small single bubbles have higher mass transfer efficiency. The daughter bubbles of cutting behaviour and initial side-by-side bubbles of coalescence behaviour als
