Molecular Dynamics Simulation of Sedimentation

Abstract

This paper describes the application of a Molecular Dynamics (MD) computer simulation technique which was used to study the sedimentation process. We considered N macroscopic size spherical particles in a viscous fluid subject to gravity and interparticle forces. Calculations were performed for three different particle sizes for both monomodal and bimodal particle size distributions. The monomodal results showed a size dependent packing effect, while with bimodal distributions fractionation was found to occur, giving rise to a layer of smaller particles on the top of the sediment.
