produce density-dependent segregation of large objects, through a buoyancy force. A criterion for the onset of fluidization …

We present a hydrodynamic theoretical model for “Brazil nut” size segregation in granular materials. We give analytical … propose a new mechanism for this particle size-segregation due to buoyant forces caused by density variations which come from …

We present a numerical study of the flow segregation problem in bidimensional piles. To simulate the pile formation, we … and the size ratio between them. The different segregation patterns arising after the pile is finished are studied by … analyzing the spatial distribution of the grains. Two different segregation indices are defined and evaluated over the piles …

Assuming the aggregates of a single chiral component as a pure phase, chiral segregation can be considered as a … segregation can be considered as phase equilibrium. The standard mechanism to understand phase equilibrium considers the complete … effect that repulsions and attractions have on chiral segregation we study a two-dimensional model, bent hard needles model …

We study the statistical mechanical conditions under which segregation of racemic mixtures of chiral molecules is … pure and racemic systems. We find that for this simple model segregation is generally possible in the very high density …

to segregate. We focus here on the segregation that occurs in the cross-section of the cylinder using short cylinders … first. Results of experimental and modelling studies of segregation are reviewed for density-induced radial segregation of … equal sized particles, and size-induced radial streak formation. Experimental results for size-induced radial segregation …

A hybrid computer simulation is used to study the effect of heterogeneous matrix density (pb) on the segregation and … external field. Size of molecular aggregates is found to increase with the matrix density, a polymerization-induced segregation …
