Abstract
The formation of a gas filtration combustion wave by a heated region of an inert porous medium is studied by numerical simulation. The mechanism of formation of the combustion wave is described. Dependencies of the time of wave formation on the feed rate of the gas mixture, the temperature of heated region of the porous medium, and its length were obtained. The ignition limits of the filtration combustion wave were found.
