This dissertation contributes to the theory of segregation and methodologies to measure it. The first two chapters focus on the traditional problem of quantifying segregation in traditional survey data through segregation indices. Segregation indices describe the segregation of an environment with one number – usually from 0 to 1. The...
Although flowing granular materials have been formally studied for over two hundred years, their behavior is still poorly understood relative to fluids, solids, and gases. Sheared granular materials with differing particle properties (e.g., size, density, shape) segregate (de-mix) due to percolation (small particles fall between large ones) and buoyancy (light...
Segregation of polydisperse granular materials remains to be a challenging problem in many industrial processes. However, most studies have focused either on bidisperse (two different particle size species) materials, which are not representative of most real mixtures, or on polydisperse materials in an idealized simple geometry. Additionally, most studies have...
