Abstract

This research aims to study dynamic and static conditions aspect 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 the standard deviation value of particle diversity in two dimensional simulation of polydisperse particles. The results of simulation are images 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 repose of pile, and otherwise the greater standard 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.
