摘要：In this work, a novel approach for investigating accurate CO2 bubble dynamic characteristics during CO2 adsorption process by monoethanolamine solution in Taylor reactor is developed. Visualization experiment and image processing is carried out for obtaining the basic data of mass transfer coefficient to provide reliable parameter in proposed model. The flow field characteristics, bubble force analysis and motion mode, and enhancement mechanism of mass transfer, are all investigated in detail based on the above approach. The grid independence and comparison between simulation and experimental results both prove this approach accurate and reliable. With the improvement of the rotational Reynolds number, the maximum value of turbulent kinetic energy in the Taylor reactor can increase by approximately 9 times, while the average rising velocity of the bubble gradually decreases, and the decrease amplitude of the average velocity becomes larger, whose decrease rate could reach up to be 73 %. It finds that the dynamic balance of buoyancy and axial drag force contributes to the transformation of the bubble motion mode. Benefiting from the extending residence time and promoting surface renewal as the rotational Reynolds number increases, the mass transfer coefficient between CO2 bubbles and the amine solution shows an upward trend, which can achieve an enhancement of approximate 2.5 times. It will provide a reference for the accurate simulation of the dispersed phase characteristics involved in the chemical reaction process in the multi-phase flow system.
