Zusammenfassung:	The capillary driven seepage in porous media under microgravity conditions is investigated. Experiments on the flow of a liquid in an inhomogeneous artificial porous medium are presented. A non-stationary mathematical model of the flow of a multiphase fluid in a sample of a porous medium is described. The experimental data are compared with the results of a three-dimensional numerical simulation of the multiphase seepage process. The behavior of the imbibition front when passing through a boundary of medias with different permeability is investigated.
