Abstract

Molecular dynamic simulations of the permeation of single and mixture gases of He and Ar through an inorganic membrane are presented. The calculated permeabilities are in favor of the Knudsen diffusion mechanism. Since He is lighter than Ar, its permeability is larger and therefore it permeates first. Therefore, in the vacuum phase the amount of He is larger than that of Ar. This shows the ability of MD calculation on estimating permeability.
