Controlling Segregation and Convection in Vibrofluidised Granular Media — •Christopher Windows-Yule1,3, Anthony Rosato2, and David Parker3 — 1Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany — 2New Jersey Institute of Technology, Newark, NJ, USA — 3University of Birmingham, Edgbaston, Birmingham, UK
The convective and segregative behaviours of granular materials are of great relevance to myriad industrial and natural processes, yet - despite significant research - remain incompletely understood and infamously difficult to control. In this talk, we detail a series of combined experimental and simulational studies in which we elucidate a deep interrelation between these two important phenomena, and novel manners in which this interrelation may be exploited. In particular, we demonstrate manners in which careful manipulation of the geometry and excitation method of a vibrofluidised system may be used to augment, reduce, induce, suppress and otherwise control both convective and segregative phenomena.
