Two Dimensional Simulation of Deposited Polydisperse Particles

Abstract

This research aims tostudydynamic and static conditionsaspect deposition of particles.Simulation applies Granular Dynamics model to describe contact forces simultaneously.The movement of particles forms a trajectory.The trajectory of particles resolved by Gear Predictor-Corrector method. Simulation involved a variation of thestandard deviation value of particle diversity in two dimensional simulation of polydisperse particles. The results of simulation areimages of deposition process for every time iteration until the pile of particles in static condition. Conclusion is the smaller standard deviation value, cause the greater angle of reposeof pile, and otherwise the greaterstandard deviation value, cause the smaller angle of repose of pile. So, the standard deviationsize diversity of particles is inversely proportional height and slope of forming pile structure.

Simulation of Heterogeneous Particle Deposition using Digital Visual Fortran

“…We have studied a simulation of deposition of polydisperse particles that varies the value of the standard deviation with respect to the effect on the shape of the pile. The result showed that the standard deviation variation in particle diameter size was inversely proportional to the height and angle of inclination of the pile structure formed [10].…”
