Abstract: Molecular dynamics calculations of the ratio DDE (where D is the self-diffusion coefficient and DE is the Enskog dense gas diffusion coefficient) for a dense hard-sphere fluid, done previously for systems of 128,250 and 432 particles, have been extended to systems of 1024, 2000 and 4394 particles for a density corresponding to VV0 = 2.0 (where V0 is the volume of close-packed hard spheres). The results confirm that DDE has only a very slight number dependence for systems of more than 250 particles.
