Abstract
We present a first experimental study of densityinduced segregation within a threedimensional, vibrofluidised, ternary granular system. Using Positron Emission Particle Tracking (PEPT), we study the steadystate particle distributions achieved by binary and ternary granular beds under a variety of differing system parameters. In doing so, we determine the extent to which the segregative processes in ternary systems resemble their comparatively wellresearched binary counterparts. We examine the influence of particle elasticity on the system, demonstrating the existence of a significant parameter range for which the effects of inelasticityinduced segregation may be safely neglected. Finally, we investigate the existence of a causal link between convective motion within a system and the segregative behaviours observed.
