Abstract

The competition between granular mixing and segregation patterns in a two orthogonal axes rotating-rocking sphere was studied. The chaos and order investigation corresponded to the continuous flow regime, with the flow within the sphere being three-dimensional and time-periodic. The results show remarkably robust segregated bands that survived the rocking amplitudes as large as 60 degrees over a wide frequency range. The space-time plots of the segregated patterns were also obtained by using a continuum flow model.
