The method of spatial averaging is apphed to derive a macroscopic form of Fick's law for unsteady diffusion through a rigid porous medium The validity of this form is found to be restricted by the requirements that diffusion is quasi-steady on a pore scale and that interphase mass transfer rates dep

## Abstract Porewater fluxes into or out of the sediments in aquatic systems are frequently estimated using Fick's First Law. This assumes that diffusive processes control the transport of nutrients. As a corollary, advection, bioturbation and chemical processes are assumed not to be significant. T

Stefan-Maxwell model (SMM) and simple Fick's model (FM) type of relations both including Knudsen diffusion for the calculation of species mole fraction distribution inside the porous anode of a solid oxide fuel cell (SOFC) were compared and it was found that at low current densities the models agree
