Abstract:
Discrete element method (DEM) has been developed in an integrated software system to study ceramic particle suspension and colloidal forming process recently [1, 2, 3]. Particle interactions such as van der Waals attraction, electrical double-layer repulsion, and short-range adhesive contact as well as frictional drag, rotational resistance, hydrodynamic lift, buoyancy and gravitational forces have been incorporated. In this study, Brownian dynamics that mimics the effects of collisions with solvent molecules is developed and integrated into the DEM simulation to study the agglomeration ratio of nanosized SiC particles in plating solution (more ...)
