Abstract

Going with the grain The nature of the random assembly of granular particles is a fundamental and ancient problem in physics and mathematics, with practical applications in situations as different as oil extraction through porous rocks, grain storage and the manufacture of tablets from powders. To date there is no known simple underlying mechanism for granular particles analogous to crystalline ordering. A team from the Center for Soft Matter Research at New York University has measured the packing of polydisperse emulsion droplets, finding that the complexity of the global packing structure can be understood in terms of a 'granocentric' view. A statistical model based on two simple, local parameters — the available space around a particle and the ratio of contacts to neighbours — successfully predicts both the local and global characteristics of packings, including their connectivity and density.
