Abstrac-A method for determining a type of pore-size distribution from diffusion measurements is presented. A Wick+Kallenbach experiment, for measuring diffusion fluxes within porous materials, is carried out over a significant portion of the transition range between Knudsen flow and bulk diflusi
The application of the converging-diverging pore model, previously developed for the simulation of structural effects on the diffusion of nonadsorbed gases in porous media, to surface transport is described. Good agreement with experimental results reported for surface diffusion of propane and neope
