Filtration combustion inside a porous cylindrical pipe with axial gas flow

Abstract

Abstract The filtration gas combustion in a porous tube with injection of a combustible mixture through the end surface of a porous cylindrical tube is theoretically studied. The simulation of the filtration gas combustion was carried out in the framework of the two-temperature thermal-diffusion model. Numerical modeling allowed to estimate the range of gas flow rates at which a stable combustion regime is observed, to find the temperature distribution in the gas and the porous body, and to evaluate the radiation fluxes inside the reactor.
