Diffusion in concentrated hard sphere dispersions: Effects of two and three particle mobilities

Abstract
Using the Verlet–Weis hard sphere radial distribution functions and the Monte Carlo method we calculate the short time self- and mutual-diffusion constants for a hard sphere dispersion at volume fractions up the disorder/order transition. The computations are based on two and three particle mobility tensors. The results show that the two particle mobility tensor alone is completely inadequate at high particle concentrations and considerable improvement is obtained when three particle interactions are included.
