| Abstract: | In a set of vibrating quasi-two-dimensional containers with the right-hand sidewall bent inward,
three new segregation patterns have been identified experimentally including a Two-Side segregation Pattern, a Left-hand Side segregation Pattern and a pattern where big particles aggregate to the upper left part of the container. In a container with small bending degree, either the two-side
segregation pattern or the left-hand side segregation pattern is stable, which is determined by the initial distribution of particles. |
