Abstract:
An experimental method for studying the combustion of porous specimens under non-one-dimensional filtration of a gaseous reagent is proposed. Propagation of a surface-combustion moving normally to the gas-permeable lateral surface of a specimen was observed in situ for the first time. When the surface fronts meet at the center of the specimen, the temperature increases, which explains previous experimental results.
Keywords:surface combustion, non-one-dimensional filtration, metal powders, superadiabatic heating, chromium nitrides.
