Duane:
Here are the references to the segregation phenomena
in granular media (it sounds better than
"sandpiles" when talking to funding agencies) I talked
about Wednesday.
The Resource Letter is an annotated bibliography to the literature.
"Reversible Axial Segregation of Binary Mixtures of Granular Materials", K.
M. Hill and J. Kakalios, Phys. Rev. E 49, R3610 (1994).
"Reversible Axial Segregation of Rotating Granular Media", K. M. Hill and
J. Kakalios, Phys. Rev. E 52, 4393 (1995).
"Magnetic Resonance Imaging of Axial Segregation of Granular Media", K. M.
Hill, J. Kakalios and A. Caprihan, Phys. Rev. Lett. 78, 50 (1997).
“Phase Diagram for Avalanche Segregation of Granular Media”, J. Koeppe,
M. Enz and J. Kakalios, Phys. Rev. E 58, R4104 (1998).
“Dynamic Angle of Repose as a Function of Mixture Concentration: Results
from MRI Experiments and DEM Simulations”, K. M. Hill, J. Kakalios, K.
Yamane, Y. Tsuji and A. Caprihan, Proceedings of ‘Powders and Grains
97’, (A. A. Balkema, Rotterdam) 483 (1997).
“Granular Physics or Nonlinear Dynamics in a Sandbox”, J. Kakalios,
Resource Letter GP-1, American Journal of Physics 73, 8 (2005).
Enjoy!
