Abstract
The dynamics of a granular mixture can differ significantly from those of a same-size flow. For example, shearing of granular materials often leads to unwanted segregation of particles of different sizes. This research uses both experiments and discrete element computer simulations to study the segregation occurring in a cylindrical Couette flow. Both experiments and simulations show a complex segregation pattern in which the concentration of large particles varies with both the radial coordinate and the angular location in the cylinder. The large particles rise to the free surface at the top of the cylindrical container and also line the outer cylinder. The number of layers of large particles around the stationary outer cylinder varies with the angular coordinate.
