Abstract
The transition of a filtration reactive flow in a double porosity medium into a self-oscillating mode is studied. Flow stability is analyzed using numerical methods for solving multiphase filtration equations in a medium with double porosity. The region of development of self-oscillations is investigated depending on the external parameters of the system and the properties of the reagents.
