Molecular Dynamics Simulation of Smaller Granular Particles Deposition on a Larger One Due to Velocity Sequence Dependent Electrical Charge Distribution

摘要

Deposition of smaller granular particles on a larger nucleus particle has been simulated in two‐dimension using molecular dynamics method. Variation of sequences of velocity of deposited particles is conducted and reported in this work. The sequences obey a normal distribution function of velocity with the same parameters. It has been observed that for velocity in range of 0 to 0.02 the densest deposited site (15-17 % number of grains) is located at about angle π/4 where location of injection point is π∕4. And the less dense is about π/4+π/4. Different sequences give similar result.
