TL;DR: In this paper, the authors developed and implemented a theoretical model that captures the interplay between advection, segregation and diffusion in size bidisperse granular materials, and the model yields two dimensionless control parameters, both of which are only functions of control parameters (feed rate, particle sizes and system size) and kinematic parameters (diffusion coefficient, flowing layer depth, and percolation velocity).

TL;DR: In this article, the authors developed and implemented a theoretical model that captures the interplay between advection, segregation, and diffusion in size bidisperse granular materials, and the model yields two dimensionless control parameters, both of which are only functions of physically control parameters (feed rate, particle sizes, and system size).

TL;DR: In this paper, the authors developed a model for shear-induced segregation in dense mixtures of different sized particles, which is comprised of two primary parts: a tendency of a gradient in kinetic stress, associated with velocity fluctuation correlations, to drive all particles toward regions of low shear rate.

TL;DR: In this article, the authors performed discrete element method simulations to study granular flows in quasi-two-dimensional bounded heaps and showed that the velocity profile normal to the overall flow, which is important in understanding segregation, can be predicted analytically from the streamwise velocity and matches the simulation results.
