摘要：Interphase mass transfer in gas-liquid bubble columns is commonly modeled using three distinct theoretical frameworks: single-bubble theory, gas-liquid slip velocity assumption, and eddy-bubble interactions. This study presents, for the first time, a comparative computational fluid dynamic-population balance model (CFD-PBM) evaluation under both co-current and counter-current flows, systematically assessing five established models & horbar;Ranz-Marshall and Brauer (single-bubble model), Higbie and Bird (slip velocity model), and Kawase (eddy cell model)& horbar;within the ANSYS Fluent two-fluid framework. The simulations are rigorously validated against experimental CO2 absorption/desorption data encompassing both co-current and counter-current flow configurations. Results indicate that the Kawase eddy cell model shows agreement within +/- 15% with experimental measurements, particularly under counter-current conditions, due to its incorporation of turbulence effects. While the single-bubble model (Brauer) and the slip velocity approach (Higbie and Bird) reproduce qualitative trends, they exhibit considerable quantitative deviations. The Ranz-Marshall model proves inadequate for accurate mass transfer predictions. Analysis of bubble size distribution reveals its strong dependence on flow regimes. Notably, counter-current operation significantly enhances mass transfer performance compared to co-current flow, primarily through increased gas holdup and enhanced turbulent mixing. These insights offer valuable guidance for both model selection and the design optimization of bubble column reactors.
