Brownian dynamics simulation of magnetic colloid aggregation

We have done simulations of aggregation of magnetic colloids at relatively high solids fraction, using new high-efficiency algorithms to deal with the long-range magnetic forces. We have included the effects of viscous damping on both translational and rotational motions. We have calculated bond-angle statistics that give information about the short-range structure of flocculated dispersions which will influence the rheological and magnetic properties.
