| Research Abstract |
We use visualization to investigate the structure of the microscale three-phase flow induced by microbubbles and small particles. In particular, we study the effect of small particles with different specific gravities on the gas-phase flow. The mean kinetic energy of the gas-phase is significantly lower in the three-phase flow than in the flow with only microbubbles. This results from ignificant suppression of the interaction of bubble plumes by the small particles. Moreover, the mean kinetic energy of the gas-phase in the three-phase flow is strongly dependent on the specific gravity of the small particles
