Abstract
In order to study distribution properties of different types of heavy particles in light media and to link macro-properties of a system with its micro-structures, radial distribution functions(RDF) of partly charged metallic particles in uni- and bi-polar systems at various shear rates were investigated by Brownian dynamics simulation. The results are good in agreement qualitatively or quantitatively compared with ones in non-polar systems and other works. The investigation indicates that dispersibility of the particles in the uni-polar system of high ionic concentrations is the largest. Therefore, it is the most unfavored to grow into clusters for precipitation. The dispersibility in the bi-polar systems is less than that in uni-polar systems, but larger than that in non-polar systems. Furthermore, all the RDFs at the same shear rates in three systems approach a limit, which implies that a threshold value exists.
