Review and Perspectives on CO₂ Bubble Dynamic Characteristics in Different Liquids during Carbon Capture, Utilization, and Storage Process

Abstract

Carbon dioxide (CO2) 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 CO2 bubbles in different liquids in CCUS, the motion mechanism of CO2 bubbles was integrated, and the effects of different liquid characteristics and different external conditions on the dynamic characteristics of CO2 bubbles were classified and summarized. At the same time, the research progress of numerical simulation on CO2 bubble dynamics is reviewed. Therefore, approaches and methods that can be further explored in theoretical analysis, experimental research, and numerical simulation of CO2 bubble dynamics are proposed, which can provide reference and guidance for engineering practice, especially CCUS technologies.
