Abstract

•Brownian dynamics simulation method is adopted to study the transport phenomena of Brownian particles in porous media.•The Voronoi and regular triangular networks of the same coordination number are adopted to represent porous media.•We find that the particle’s breakthrough concentrations for these two networks are of the same values.•But with different breakthrough moments and permeability reduction rates.

This paper employs the Brownian dynamics simulation method to compare the particle breakthrough history and permeability reduction of porous media between Voronoi and regular triangular networks of the same coordination number. For the case of transporting Brownian particles through these two networks, it is found that their breakthrough concentrations are of the same value, but have different breakthrough moments and permeability reduction rates under either favorable or unfavorable deposition conditions. Same results are also obtained for the non-Brownian particles.
