Filtration of a gas-liquid medium in a plane horizontal region
In describing two-phase filtration flows, along with problems of constructing a model of a physical process, there are difficulties of the computational character as well, which are associated with the manifestation of different-scale filtration processes of phases. The paper presents a universal computing technology that implements the van Genuchten mathematical model. An example of two-phase filtration in a plane region is presented.
