Abstract: We use the concept of rotational stability to explain the axial segregation of granular mixture inside a rotating horizontal container. We consider the core of radially segregated granular mixture as a dissipative rotating rigid body.… read more here.

DOI: 10.1007/s10035-019-0954-y
Abstract: Frustration arises for a broad class of physical systems where confinement (geometric) or the presence of a perturbation (kinematic) prevents equilibration to a minimum energy state. By varying the diameter ratio and packing fraction in… read more here.
