Discrete sedimentation model for ideal suspensions

Abstract

The sedimentation process of ideal suspensions is simulated using a discrete model in which gravitational, hydrodynamic, particle interaction and dispersive motions are considered as competitive processes. These mechanisms define motion rules that are implemented in regular two-dimensional lattices. Results show that the model is capable of producing the whole spectrum of particle-settling of ideal suspensions. Computer simulation results for the batch settling of rigid spheres in water are obtained for monodisperse systems. Results compared fairly well with experimental data. (C) 2000 Elsevier Science B.V.
