Enhanced Diffusion of a Needle in a Planar Array of Point Obstacles
Enhanced Diffusion of a Needle in a Planar Array of Point Obstacles
The transport of an infinitely thin, hard rod in a random, dense array of point obstacles is investigated by molecular dynamics simulations. Our model mimics the sterically hindered dynamics in dense needle liquids. Transport becomes increasingly fast at higher densities, and we observe a power-law divergence of the diffusion coefficient …
