Ignition of a Filtration Gas Combustion Wave by a Heated Region of a Porous Medium

The ignition of a filtration gas 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. Dependences of the time of wave formation on the velocity of the gas mixture, the temperature of the heated region of the porous medium, and its length were obtained. The existence of ignition limits of the filtration combustion wave was found.
