Simulation of Vibration-Induced Segregation of Equal-Sized Bronze and Glass Spheres

چکیده
The influence of the surrounding air on the dynamics of fine granular material is becoming an increasingly topical area of research interest. While for large granular particles (diameter > 1 mm) the effect of the gas phase can usually be ignored, for smaller particles the ambient air can have a pronounced influence. One of the most striking examples of the effect of air was demonstrated in the experiments by Burtally et al. A bed of fine (110 micron) equal-sized bronze and glass spheres was found to segregate under vertical vibrations at atmospheric pressure. No significant segregation was observed under vacuum conditions.

Interstitial gas and density segregation of vertically vibrated granular media.
We report experimental studies of the effect of interstitial gas on mass-density segregation in a vertically vibrated mixture of equal-sized bronze and glass spheres. Sufficiently strong vibration in the presence of interstitial gas induces vertical segregation into sharply separated bronze and glass layers. We find that the segregated steady state (i.e., bronze or glass layer on top) is a sens...
متن کاملSimulation study of air-induced segregation of equal-sized bronze and glass particles.
We have investigated the effect of air on the density segregation of fine, equal-sized bronze and glass particles under vertical sinusoidal vibrations by numerical simulation, using a hybrid granular dynamics-computational fluid dynamics model. We find both the bronze-on-top and the sandwich configurations as observed in previous experiments. The simulations allow us to give a detailed explanat...
متن کاملSimulation of density segregation in vibrated beds.
We have investigated by numerical simulation the density segregation of fine equal-sized bronze and glass particles subject to vertical vibrations. The model was found to be capable of predicting the two main segregation forms ("bronze on top" and "sandwich") in roughly the same regions of the phase diagram as was found experimentally by Burtally We investigated the effects of pressure air forc...
متن کاملSegregation patterns of an equidensity TiO2 ternary mixture in a conical fluidized bed: CFD and experimental study
In this study, an Eulerian-Eulerian multi-fluid model (MFM) was used to simulate the segregation pattern of a conical fluidized bed containing ternary mixtures of equidensity TiO2 particles. Experimental 'freeze–sieving' method was employed to determine the axial mass fraction profiles of the different-sized particles, and validate the simulation results. The profiles of mass fraction for larg...
متن کاملCFD simulation for segregation behavior of a ternary mixture in a bubbling fluidized bed: effect of solid wall boundary condition
Abstract The effect of the solid–wall boundary condition on the segregation behavior of a sand ternary mixture differing in size but having the same proportion has been investigated in a gas–solid bubbling fluidized bed. A multi-fluid computational fluid dynamics model incorporating the kinetic theory of granular flow has been used. The mass fraction profiles of the different-sized partic...
