Effective diffusion in the region between two surfaces
arXiv:1511.06166 · doi:10.1103/PhysRevE.94.022121
Abstract
The purpose of this paper is to provide a formula for the effective diffusion operator obtained by projecting the 3-dimensional diffusion equation onto a 2-dimensional plane, assuming reflective boundary conditions at two surfaces in 3-dimensional space. The formula provided corresponds to the case of finite transversal stabilization rate.
