A Microscopic Description of the Granular Fluidity Field in Nonlocal Flow Modeling
Qiong Zhang, Ken Kamrin
A recent granular rheology based on an implicit `granular fluidity' field has been shown to quantitatively predict many nonlocal phenomena. However, the physical nature of the fiel…
General scaling relations for locomotion in granular media
James Slonaker, D. Carrington Motley, Qiong Zhang +4
We derive a general dimensionless form for granular locomotion, which is validated in experiments and Discrete Element Method (DEM) simulations. The form instructs how to scale siz…
Coupled dynamics of flow, microstructure, and conductivity in sheared suspensions
Tyler Olsen, Ahmed Helal, Gareth McKinley +1
We propose a model for the evolution of the conductivity tensor for a flowing suspension of electrically conductive particles. We use discrete particle numerical simulations togeth…
