The effect of diffusion of the main reactants on flame speeds in gases

Abstract

The general equations of a single-reaction flame are written down, allowing for the diffusion of the main reactants and products. It is shown that the pressure-dependence of the flame speed is not altered by the consideration of diffusion. A method of successive approximation is applied to the equations with diffusion, giving an easily applied solution for the speed of a flame maintained by a single reaction whose rate depends only on the temperature and the concentrations of the reactants.
