Abstract:The rising behavior and mass transfer process of CO 2 bubble in the water were simulated and analyzed. The VOF model was applied to track the interface boundary. The CO 2 was added through an orifice with a diameter of 2.4 mm at the bottom. The bubble shapes through the rising process were shown and the aspect ratio was used to reflect the bubble deformation. The flow patterns around the bubble were also analyzed and its influence on mass transfer was discussed. The results show that the bubble equivalent diameter keeps constant though the bubble shapes change dramatically. Besides, the mass transfer process in the bubble rise section is different from that in the bubble formation and detachment sections
