Shear-driven size segregation of granular materials: Modeling and experiment

PHYSICAL REVIEW E, 81(5).

By: L. May n, L. Golick n, K. Phillips n, M. Shearer n  & K. Daniels n 

TL;DR: The Gray-Thornton model of segregation is applied to a granular flow with an exponential shear profile, and the model successfully captures the presence of a fast mixing process and relatively slower resegregation process, but the model predicts a finite resegregation time, while in the experiment resegregation occurs only exponentially in time.

Mixing and segregation rates in sheared granular materials

PHYSICAL REVIEW E, 80(4).

By: L. Golick n & K. Daniels n 

author keywords: granular materials; mixing; particle size; percolation; segregation
TL;DR: This work experimentally investigates sheared dense bidisperse granular materials as a function of the size ratio of the two species and finds that the mixing rate at low confining pressure behaves as expected from percolation-based arguments, but observes an anomalous effect for the resegregation rates.
