    "abstract": "The filtration of fluid in 2D porous medium is simulated by the molecular\ndynamics technique. The high concentration of fluid is created at the initial\npoint in time and the number of fluid particles is investigated in all porous.\nThe concentration of particles pores and parameters of interaction potentials\nis varied. In all cases the particles concentration decay is well described by\nexponential functions. The decreasing of the interpore channels leads to the\nincreasing of the relaxation time and does not depend on the system size. This\nphenomenon is observed in real filtration processes.",
