Radial segregation through axial migration
We investigate the interplay of radial size and density segregation in a three-dimensional cylinder numerically. By fixing the size ratio of a binary particle mixture and varying the density of the smaller particle, we find a very surprising segregation dynamics in the case of a counter-balance of s...

| Zusammenfassung: | We investigate the interplay of radial size and density segregation in a three-dimensional cylinder numerically. By fixing the size ratio of a binary particle mixture and varying the density of the smaller particle, we find a very surprising segregation dynamics in the case of a counter-balance of size segregation by density segregation. It can be best described by a "segregation wave” propagating through the system which has dissolved completely by the time it has reached the cylinder boundary. |
