Abstract: In the present paper it is considered a two-component multiphase isothermal flow of compressible fluids in porous media with mass exchange between phases. The system of equations has discontinuous solutions with concentration waves. For the equations the auto modeling decisions “traveling wave” are found. Such decisions describe running waves of concentration at continuous pressure. The cases, when on the one hand of concentration jump the solution is in single-phase state, and with another is in a two-phase state, are considered.
