Single droplet breaking after interaction with vortex ring
Original language description
The study of the droplet breakup is based on the experimental visualisation of a single droplet interacting with a vortex ring. The experimental design allows control of both the vortex ring inertia and the droplet size. A kerosene droplet breaking in distilled water is studied. A high-speed camera is used to record the entire interaction process and the breakup frequency is evaluated. The breakup frequency is compared with data obtained for bubbles interacting with the vortex ring under the same conditions and with theoretical models available in the literature. Appropriate scales are defined to compare bubble and droplet experimental data. The Weber number relevant to bubble breakup is based on the density of the continuous phase, whereas the Weber number relevant to droplet breakup is based on the density of the dispersed phase. The time scale relevant to droplet breakup must reflect the density ratio of both phases. Although the comparison of all experimental data shows reasonable agreement with results obtained in turbulent flows, the density ratio is not sufficient to unify the description of bubble and droplet breakup.n
