Filtration combustion of gases

The present paper is devoted to the theoretical and experimental investigation of the characteristics of the filtration combustion wave of gaseous systems. The process of filtration combustion of a gas in an inert porous medium is carried out. The possibility is shown for the propagation of combustion waves counter to the flow and in direction of the flow. A two-temperature model of the filtration combustion of gases has been constructed and validated which describes the effect of the parameters on the characteristics of the process. The presence of two regimes of filtration combustion of gases is established: low velocities with a strong thermal interphase interaction, and high velocities with a weak thermal interaction. An important element in the low velocities regime is the recuperation of heat in the cycle.
