Study of pulsating flow of viscous two-phase media in a flat porous pipe considering particle gravity force

This paper examines the issues of unsteady pulsating motion of a viscous two-phase medium in a flat porous pipe taking into account the gravity of a solid particle in a two-dimensional formulation. Changes in the longitudinal velocity profiles of mixtures and the distribution of the volumetric content of the carrier and solid phases in a flat pipe, as well as the rate of liquid infiltration, the distribution of pressure and the volumetric content of the carrier and solid phases in pipes with porous walls have been studied.
