New Insight into Pseudo-Thermal Convection in Vibrofluidised Granular Systems.

ABSTRACT: Utilising a combination of experimental results obtained via positron emission particle tracking (PEPT) and numerical simulations, we study the influence of a system's geometric and elastic properties on the convective behaviours of a dilute, vibrofluidised granular assembly. Through the use of a novel, 'modular' system geometry, we demonstrate the existence of several previously undocumented convection-inducing mechanisms and compare their relative strengths across a broad, multi-dimensional parameter space, providing criteria through which the dominant mechanism within a given system - and hence its expected dynamics - may be predicted. We demonstrate a range of manners through which the manipulation of a system's geometry, material properties and imposed motion may be exploited in order
