Table 1.
Ratios of the effective diffusion coefficients found in Brownian dynamics simulations to their theoretically predicted counterparts, Eq. (3), at different values of the length and radius of the narrow sections. The simulation results were obtained at lw = R by averaging over 5 × 104 trajectories. The relative errors of these results do not exceed 2%.
