A new method for determining the maximum value of the van der Waals force, Fv,max, has been developed to analyze the dispersion and aggregation behavior of primary particles in a suspension. The simulation method considered the van der Waals force, the electrical double-layer force and the lubrication force as remote inter-primary-particle interaction forces. Distinct Element Method (DEM) was applied to tracking the motion of primary particles, and DEM was coupled with Computational Fluid Dynamics (CFD) by DEM-CFD coupling model to represent the motion in liquid. Aggregate size distributions (ASDs) were measured and simulated at different pHs and shear rates in order to determine the Fv,max ..View full abstract
