2-D Brownian motion in a system of reflecting barriers: effective diffusivity by a sampling method
(Institute of Physics, 1994-02-07)
We study two-dimensional Brownian motion in an ordered periodic system of linear reflecting barriers using the sampling method and conformal transformations. We calculate the effective diffusivity for the Brownian particle. When the periods are fixed but the length of the barrier goes to zero, the effective diffusivity in ...
