On the basis of the previously developed mathematical model, the dynamics of the flow of a viscous liquid with particles in a porous medium is studied. The model takes into account the hydrodynamic interaction of all particles, both moving and stationary. For computer simulation of particle dynamics in such currents, a developed software package is used. A numerical calculation of the dynamics of a viscous liquid with particles at a given pressure gradient in two model structures of a porous medium, formed respectively of 450 and 478 particles of effective size is carried out. The dimensions of the dispersed particle placed in a viscous liquid were 0.3 and 0.2 of the effective particle size. The flow of a viscous liquid with a pressure gradient was specified. It is found that in the presence of a pressure gradient, the movement of the dispersed particle in the porous structure has a component directed against the flow of liquid outside the structure.
