A model for the combustion of pyrophoric metal foils has been developed. The diffusive mass transport, heat transport, and chemical reactions of porous iron foils have been described. The temperature and radiated energy of these materials has been predicted as a function of the physical characteristics of the material (porosity, pore size, specific surface area) for different atmospheric conditions (temperatures and oxygen concentrations varied with altitude and wind velocity).
