The aim of this project is to understand the nature and cause of segregation in rotating drums. So far work has focused on using particle simulations and optical experiments to investigate the effect of the convexity versus concavity of the drum [U27]. Here, it was found that axial accelerated and controlled by switching from convex to concave shapes. More recently, PETP experiments have started to be used and the effects of the length of the drum is being worked at in more detail.
