The mechanisms of diffusion processes in porous media have not yet been thoroughly studied. As a rule, when studying diffusion processes in such materials, Fick’s laws are taken as a basis, which are refined by introducing additional force constants that affect the elementary act of diffusion. Since the characteristics of local centers on the walls of the tracks are determined by the defective structure of the inner surface of the tracks, it is impossible to formulate a universal formula describing the diffusion process. However, the diffusion mechanism can be clarified using a computer experiment.

摘要

The mechanisms of diffusion processes in porous media have not yet been thoroughly studied. As a rule, when studying diffusion processes in such materials, Fick’s laws are taken as a basis, which are refined by introducing additional force constants that affect the elementary act of diffusion. Since the characteristics of local centers on the walls of the tracks are determined by the defective structure of the inner surface of the tracks, it is impossible to formulate a universal formula describing the diffusion process. However, the diffusion mechanism can be clarified using a computer experiment.
