Particle Segregation in Dense Granular Flows: Supplemental Video 10

A supplemental video from the 2018 review by John Mark Nicholas Timm Gray, "Particle Segregation in Dense Granular Flows," from the Annual Review of Fluid Mechanics.

Shown: Movie showing the formation of the Catherine wheel and radial segregation patterns in a thin rotating drum (Gray & Hutter 1997; Gray & Chugunov 2006). The drum is initially shaken horizontally so that all the large white sugar particles are on the front face and the small grey iron spheres are on the rear side.
