Dense granular flow - A collaborative study
Abstract
© 2015 Elsevier B.V..The International Fine Powder Research Institute (IFPRI) has
funded an extensive program in dry powder and granular flows, including a focused
study on dense flows of interest to a range of industrial handling and process unit
operations, especially dense flows at relatively high shear rates. The dense flow
program included experimental studies of granular rheology in 3D axial Couette and
2D hopper geometries, wherein the effect of force chains and jamming interactions
were investigated as relevant to flow, stress and packing dynamics. The program cumulated
in a collaborative study funded by the NSF, wherein a group of academic collaborators
was invited to model experimental systems used in IFPRI-sponsored projects. This paper
provides a summary of the IFPRI program, details of the collaborative modeling study,
and perspective on what is needed to progress the work further.

Dr. Behringer's research interests include granular materials: friction, earthquakes,
jamming; nonlinear dynamics; and fluids: Rayleigh-Benard convection, the flow of thin
liquid films, porous media flow, and quantum fluids. His studies focus particularly
on experiments (with some theory/simulation) that yield new insights into the dynamics
and complex behavior of these systems. His experiments involve a number of highly
novel approaches, including the use of photoelasticity for probing granular
