Abstract

The device of oil-water separation enhanced by electromagnetic synergy could potentially play a pivotal role in realizing the green oil gathering and transportation pretreatment in the future. In this paper, the high-speed microscopic experiment shows that the migration mode of a single droplet under the action of the polarized electromagnetic force is not consistent with the previous theoretical analysis. Theoretical analysis shows that the longitudinal migration mode of a droplet under the polarized electromagnetic force is oscillatory displacement. However, the experimental results show that the longitudinal movement direction of a droplet remains unchanged, and there is no oscillatory displacement. Moreover, the effect of the polarized electromagnetic force on a droplet is reflected in the form of enhancing longitudinal displacement. In addition, by solving the motion equation, the velocity difference of the droplet after a period is obtained, and the influence mechanism of the polarized electromagnetic force is discussed.
