Electric dispersion is a novel and promising method for bubble dispersion. In this study, the laboratory scale bubbling reactor with nonuniform electric field was established. A high-speed camera used to observe investigate in nitrogen biodiesel up-flow system. The results showed that dynamic characteristics of dispersion, including volume, shape, rising velocity, were strongly correlated strength. could be controllably dispersed into numerous charged bubbles through equivalent diameter decreasing from 1.88 0.64 mm. As result, cluster obtained Gaussian distribution. number per cubic meter increased 5.01 × 105 5.40 107, which significantly improved gas–liquid mass transfer area. Moreover, changes gas liquid velocities had little effect on cluster. Both size density regulated by adjusting Additionally, model developed predict mean cluster, an average relative error 6.37%. Overall, would provide reference application reactors.
