It is of vital significance to investigate mass transfer enhancements for chemical engineering processes. This work focuses on investigating the coupling influence of embedding wire mesh and adding solid particles on bubble motion and gas-liquid mass transfer process in a bubble column. Particle image velocimetry (PIV) technology was employed to analyze the flow field and bubble motion behavior

and dynamic oxygen absorption technology was used to measure the gas-liquid volumetric mass transfer coefficient (

). The effect of embedding wire mesh

adding solid particles

and wire mesh coupling solid particles on the flow characteristic and

were analyzed and compared. The results show that the gas eliquid interface area increases by 33%-72% when using the wire mesh coupling solid particles strategy compared to the gas-liquid two-phase flow

which is superior to the other two strengthening methods. Compared with the system without reinforcement

k

in the bubble column increased by≥0.5-1.8 times with wire mesh coupling solid particles method

which is higher than the sum of

increases with inserting wire mesh and adding particles

and the coupling reinforcement mechanism for affecting gas eliquid mass transfer process was discussed to provide a new idea for enhancing gas-liquid mass transfer.
