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 …

gravity. At low bias, the segregation of A and B leading to a partial layering is enhanced toward the bottom. The longitudinal … profiles show segregation with different domain sizes and layering depending on the bias. Response of their steady-state flux …

individual grains. This model is generalized to take into account segregation of different types of particles, in particular the …

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 …
