“…In particular, in modeling the mass transfer between gas and liquid, dynamic Sherwood number considering bubble oscillation has been included. 177 Sommerfeld et al 173 and Gruber et al 56 studied the influences of break-up and coalescence (B&C) events on the flow field and concentrations of species in a small bubble column (BC). B&C has a significant impact on liquid-phase mixing as well as the mass transfer process.…”

“…The mass transfer process in a bubble column is highly influenced by bubble dispersion and flow structure. 177 Bubble size is an influential parameter which affects the turbulent dissipation rate of the aerator. 146 The proper determination of dynamic changes of bubble size is essential for the calculation of gas−liquid mass transfer rate.…”

The effective removal of gas phase species relies on effective gas liquid hydrodynamic contact coupling with fast chemical reaction rates. To promote mass transfer rate and the development of reagents, computational fluid dynamic modeling has long been recognized as an effective methodology for the quantification of physical and chemical parameters. The simulation of the gas liquid process involves the coupling of models including multiphase flow, turbulence, interfacial forces, mass transfer, and chemical reactions. The selection of suitable models according to practical applications has been challenging. In terms of multiphase flow, volume of fraction, Euler−Euler, and Euler−Lagrange approaches are discussed. With regard to turbulence, direct numerical simulation, large eddy simulation, and Reynolds averaged Navier−Stokes approach are compared. With respect to interfacial forces, the dominance of drag, lift, virtual mass, wall lubrication, and turbulent dispersion forces for different situations are obtained. In terms of mass transfer, the development and applications of film model, dimensionless analysis, penetration model, and surface renewal model are discussed. Different methodologies to enhance mass transfer include improvement of equipment structure, addition of nanofluid, and exposure to an energy field are summarized. To accelerate the computational process, four methods including the space−time conservation element and solution element model, compartmental model, reduction in dimension, and multiscale approach are discussed. This paper intends to provide a thorough review on the applications of different models to different situations and, in particular, to reveal the restrictions of different models. Overall, this study lays the foundation for future studies on the optimization of scrubbers for large scale practical applications. It also allows a deeper understanding of the interactions of fluid dynamics, mass transfer, and chemical reactions.

“…In recent years, Roland, Sommerfeld, Lain, and Taborda − have used the Euler–Euler and Euler–Lagrangian models for numerical simulation. The results show that these two models are suitable for the dynamics of bubbles in gas–liquid mixed multiphase flow, especially for the bubble characteristics of CO 2 bubbles in bubble columns.…”

Carbon dioxide (CO 2 ) bubbles are common during carbon capture, utilization, and storage (CCUS) processes and have many impacts on water conservancy machinery, metallurgy, and the chemical industry. To explore the dynamic characteristics of CO 2 bubbles in different liquids in CCUS, the motion mechanism of CO 2 bubbles was integrated, and the effects of different liquid characteristics and different external conditions on the dynamic characteristics of CO 2 bubbles were classified and summarized. At the same time, the research progress of numerical simulation on CO 2 bubble dynamics is reviewed. Therefore, approaches and methods that can be further explored in theoretical analysis, experimental research, and numerical simulation of CO 2 bubble dynamics are proposed, which can provide reference and guidance for engineering practice, especially CCUS technologies.

“…The most commonly used mass transfer models in CFD simulation of gas–liquid mass transfer include Higbie’s slip penetration model, Lamont’s eddy cell model, and empirical models of Sherwood ( Sh ) number. Among them, the empirical model of Sh number is mainly used for the absorption of CO 2 in NaOH solution, ,− but Darmana and Chen concluded that the empirical models of Sh number are not able to simulate the mass transfer coefficient accurately. As to the slip penetration model and the eddy cell model, due to their simple expressions, few adjustable parameters, and wide versatility, many researchers ,,− use these two mass transfer models for CFD simulation.…”

In this study, the air-blowing process of iodine in nitric acid solution was studied through experiments and computational fluid dynamic (CFD) simulation. The impact of superficial gas velocity and nitric acid concentration on the gas holdup and bubble distribution during bubbling is tested. population balance model (PBM) and interfacial area concentration model (IACM) models are selected to simulate the bubble coalescence and breakup, and the slip penetration model is used to simulate the mass transfer process. The experimental results show that the size of the bubbles in the nitric acid solution is smaller than that in the water due to Gibbs–Marangoni effect and electrical repulsive forces, resulting in a larger gas holdup and a wider bubble distribution. When the concentration of nitric acid solution exceeds 1 mol/L, the effect of nitric acid concentration variation on gas–liquid-phase hydrodynamics becomes less significant. The CFD simulation results showed that the PBM–(EMMS)Luo–Luo model can simulate the bubble coalescence and breakup in water, while the IACM–Hibiki–Ishii model is more suitable for those in nitric acid solution. In addition, it is found that the “slip penetration” model is suitable for the mass transfer calculation in the air-blowing process of iodine.
