1. Energy propagation in dense granular media
Katja Lindenberg, Department of Chemistry and Biochemistry, University of California San Diego
QUESTIONS:
How does a pulse propagate in a granular medium?
How does the physical design of the medium affect propagation?
e.g. vs vs
Initial condition
Shapes of granules
Mass and size distribution
Dimensionality vs
We have developed a binary collision approximation that permits ANALYTIC SOLUTION and consequently
FULL PREDICTIVE POWER in many cases.
Typical agreement with numerical simulations
