Molecular dynamic simulation of the fluid concentration fluctuations in twodimensional porous medium

Abstract

The filtration of fluid in 2D porous medium is simulated by the molecular dynamics technique. The high concentration of fluid is created at the initial point in time and the number of fluid particles is investigated in all porous. The concentration of particles pores and parameters of interaction potentials is varied. In all cases the particles concentration decay is well described by exponential functions. The decreasing of the interpore channels leads to the increasing of the relaxation time and does not depend on the system size. This phenomenon is observed in real filtration processes.
