The Diffusion Theory for 2D Nematic of Hard Needles

Abstract

The Enskog type theory results of the diffusion coefficients are presented for a system of two-dimensional hard needles and they are confronted to the Molecular Dynamics simulation data. The theory reproduces well not only the basic features of the diffusion in the molecular frame, but also the values obtained after transformation to the laboratory frame.
