Particle size effect on diffusion in tubes with dead ends: Nonmonotonic size dependence of effective diffusion constant
Diffusion of a spherical particle of radius r in a tube with identical periodic dead ends is analyzed. It is shown that the effective diffusion constant follows the Stokes–Einstein relation, D(eff)(r)∝1∕r, only when r is larger or much smaller than the radius of the dead end entrance. In between, D(...
