Abstract: In this paper we analyze the speed of gas flames in a combustion premixed model that consists of two species (fuel and non-fuel). The main novelty with respect to recently published papers is that here we take into account the effect of the diffusion velocities in the energy equation. This means that the speed of the traveling wave obtained by numerically solving the combustion model (i.e., a system of two coupled one-dimensional partial differential equations) is a function of the Lewis number.
