Singular behavior of a cohesive powder under horizontal vibrations
Abstract eng: We report the influence of horizontal vibrations on the time-evolution of the density of a very cohesive powder. For a wide range of vibration conditions, the kinetics of compaction presents a two time-scales behavior compared to model materials. A simple stochastic model, based on clusters of grains, has been developed to understand the compaction process, and a new empirical law proposed to describe the evolution of the packing fraction φ.
