摘要:

Rigorous bounds on the permeability of a porous medium to Knudsen flow are formulated by applying the variational procedure of DeMarcus. The bounds are expressed in terms of certain averages characterizing the random‐pore geometry. Explicit calculations are given for a model pore structure generated from randomly overlapped spheres.
