| Outline of Final Research Achievements |
It is well known that granular materials which is composed of several species tend to segregate when they are under mechanical agitation, such as shaking, flowing, and tapping as if phase separation occurs in oil/water mixutre. In this project, we experimentally studied segregation dynamics of granular materials in a rotating cylinder. We found several new spatio-temporal dynamics of segregation and proposed a phenomenological model. Numerical simulations were also carried out to investigate internal granular flow of granular media in a rotating cylinder.
