Summary on Grant Application Form |
This proposal concerns the development and implementation of numerical techniques to simulate the dynamics of granular mixtures subjected to vibration. Granular materials are widespread in nature and play an important role in many industrial processes. They also provide a testing ground for the ideas of non-equilibrium statistical mechanics. However, to date, there is no detailed understanding of the basic physical mechanisms responsible for mixing and segregation in multi-component systems, nor is there any fundamental theoretical framework to describe these phenomena.Initially we will consider single-component granular media and benchmark our simulations against experiments in a series of test simulations: first, characterisation of the flow profiles in dense granular beds under both vertical and horizontal vibration, and second, identification of the mechanisms responsible for segregation in partition experiments. We will then extend the technique to multi-component granular systems. Numerical simulations, supported by experimental observations, will be used to determine how mixing and segregation depends on the details of the granular materials and the nature of the external driving conditions.Our research will be an important step in the development of macroscopic equations of motion that govern multi-component granular flows.
