Numerical evaluation of the porous medium effective diffusivity between the Knudsen and continuum limits
A variational principle based on the mean free path kinetic theory of gases is used to calculate the effective diffusion coefficient for gaseous diffusion through a bed of overlapping solid spheres for arbitrary Knudsen number and porosity φ. Effects of tortuosity of the diffusion paths are consider...
