| Outline of Final Research Achievements |
Collective settling of fine particles in liquid have been studied numerically, theoretically and experimentally. The existence of concentration interface, which is an apparent interface between suspended particles and pure fluid, plays a significant role in the collective motion of suspended particles. We examined relative motion of particles to surrounding flow near the concentration interface microscopically and found the mechanism of collectivity of particles. We also investigated the collective settling of suspended particles in a complicated channel and develop a physical model on dispersion behavior of particle in the channel.
