Heterogeneous removal of one or more chain-carrying species at first explosion limit of hydrogen + oxygen mixtures. Part 1.—A numerical method for solution of the diffusion equations

Abstract

A numerical method has been developed for the solution of the diffusion equations which represent the mechanism of the hydrogen + oxygen reaction at the first explosion limit. Where one species is diffusing to the wall, the results agree well with those obtained by the accurate analytical theory; where two species are diffusing to the wall simultaneously, the results show that, when the destruction efficiencies for the two species differ markedly, the effect of the two removal processes is not the sum of the individual processes, but that an interaction exists between the processes.
