Abstract
Calculations using model systems are presented which illustrate the effect of macroscopic heterogeneity of the porosity on the gaseous- and surface-phase flow of gas through porous media. It is argued that macroscopic heterogeneity is likely to be present in many systems studied in the laboratory and that its effect on flow properties could be significant. Analogies with previous work on pore structure are drawn.
