“…Because of the properties of the solution itself, many scholars have studied the dynamics of CO 2 bubbles in the liquid in various ways. For instance, Gao et al 69 explored the growth and movement of a single CO 2 bubble in pure water, NaOH, NaHCO 3 solution, and sodium carboxymethyl cellulose solution using four nozzles with different radii to generate different CO 2 bubbles (as shown in Figure 2). They found that NaHCO 3 solution would inhibit the reaction between NaOH solution and CO 2 , resulting in a reduction in the change of cross-section ratio.…”

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.

“…Ma et al [27] used a new Euler/Lagrangian two-phase flow model to study the dynamics of bubble clouds excited by a sinusoidal pressure field near a rigid wall. Yang et al [28] studied the motion kinetics of carbon dioxide bubbles in different solutions and established a carbon dioxide bubble experimental platform. They conducted experiments on the growth and motion of individual carbon dioxide bubbles in five concentrations of sodium hydroxide, sodium bicarbonate solution, and five viscosities of deionized water.…”

In the process of ultrasound assisted electrochemical polishing of selective laser melting (SLM) NiTi alloy, a large number of cavitation bubbles will be generated in the anode and cathode, and these cavitation bubbles will expand and compress rapidly until finally collapse. At the moment of collapse, high temperature and high pressure will occur, and at the same time, pressure shock wave and micro-jet will be produced, which will have a certain impact on material removal during polishing. In order to explore the mechanism of ultrasonic assisted electrochemical polishing, in this paper, the dynamics of cavitation bubbles with free interface and rigid interface are analyzed by ultrasonic assisted electrochemical polishing. The dynamics models of single cavitation bubble and two cavitation bubbles are established. The fourth order Runge–Kutta method was used to solve the model numerically, and the influence of electric field intensity, initial bubble radius, sound pressure amplitude and ultrasonic frequency on the dynamics of cavitation bubble was analyzed. The results show that in the range of f = 1–10 KHz, the initial radius of bubble is 0.01–0.05 micron, the sound pressure amplitude is 103 Pa, and the electric field intensity is 104 V m−1, the cavitation movement gradually becomes regular, and it goes through a complete process of expansion, contraction and then collapse, which is beneficial to the cavitation effect. This provides a theoretical basis for further research on the mechanism of ultrasonic assisted electrochemical polishing of SLM-NiTi alloy, which is of great significance for broadening the processing of additive manufacturing parts with low cost, high efficiency, and consistent quality.

The combination of zeolitic imidazolate framework‐8 (ZIF‐8) and ionic liquids (ILs) to create porous ionic liquids (PILs) is highly significant for efficient carbon dioxide (CO2) capture and the advancement of carbon capture, utilization, and storage (CCUS) technologies. To further investigate the CO2 capture characteristics of different PILs, two different‐sized ZIF‐8 structures and two functionalized ILs were prepared. Additionally, the enhancement factor of the reaction process was calculated using the dual‐film theory and mass transfer coefficient. The results demonstrated that the original [PMIm]Cl had low CO2 absorption capacity at ambient temperature and pressure, whereas the functionalized ILs had a maximum CO2 capture capacity of approximately .31 mol/mol, with the 20 wt% concentration of tetraethylene pentamine‐2‐methylimidazole ([TEP][MIm]) exhibiting the highest CO2 capture capacity of around 1.93 mol/mol. The synthesized PILs demonstrated a maximum CO2 capture capacity of approximately 2.22 and 2.16 mol/mol at 20 and 10 wt% ionic concentrations, respectively, with a porous ionic liquid addition of 1.0/100 g. The corresponding enhancement factors were 1.53 and 1.59, respectively. These findings have significant implications for CCUS technology.
