MR Imaging of Reynolds Dilatancy in the Bulk of Smooth Granular Flows
Ken Sakaie, Denis Fenistein, Timothy J. Carroll +2
Dense granular matter has to expand in order to flow, a phenomenon known as dilatancy. Here we perform, by means of Magnetic Resonance Imaging, direct measurements of the evolution…
Core Precession and Global Modes in Granular Bulk Flow
Denis Fenistein, Jan-Willem van de Meent, Martin van Hecke
A transition from local to global shear zones is reported for granular flows in a modified Couette cell. The experimental geometry is a slowly rotating drum which has a stationary…
Universal and wide shear zones in granular bulk flow
Denis Fenistein, Jan Willem van de Meent, Martin van Hecke
We present experiments on slow granular flows in a modified (split-bottomed) Couette geometry in which wide and tunable shear zones are created away from the sidewalls. For increas…
