Hydrodynamic Theory for Reverse Brazil Nut Segregation and the Non-monotonic Ascension Dynamics
Meheboob Alam, Leonardo Trujillo, Hans J. Herrmann
Based on the Boltzmann-Enskog kinetic theory, we develop a hydrodynamic theory for the well known (reverse) Brazil nut segregation in a vibro-fluidized granular mixture. Using an a…

A note on the upward and downward intruder segregation in granular media
L. Trujillo, H. J. Herrmann
The intruder segregation dependence on size and density is investigated in the framework of a hydrodynamic theoretical model for vibrated granular media. We propose a segregation m…
