Abstract:Low density permeations of some gases (He, H2, N2, CH4, CO2 and CF4) through micro‐ and mesocarboneous pores were investigated using Knudsen and Oscillator models. Lennard‐Jones model in single layer pores was used to simulate the gas–solid interactions in the Oscillator model. The effects of the pore radius as well as the molecular size and the temperature on the pore diffusivity and the activation energy were studied. The Monte Carlo simulation was then performed to calculate the permeability of these gases … Show more

“…The membrane was subjected to a pressure gradient across its thickness while four other sides of the network were subjected to the periodic conditions [35]. The total macroscopic flow in the network was one dimensional; however, the molecules were able to diffuse in pores perpendicular to the main diffusion axis.…”

“…In the previous study [35] we investigated the effects of surface potential on the selectivity of some pure gases through meso porous membranes in low density condition. However, in this paper NCGSR are studied in the regular networks.…”

“…The Bethe network is the simplest existing network and since it has no closed loop, analytical solutions are available for such constructions. However, closed loop in the real networks plays an important role in molecular correlations which increase the tortuosity of lighter molecules [35][36][37]. PNS in more complicated networks needs a great deal of numerical calculation which can be implemented with today's computers.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
