Abstract
Numerical results reported in the literature for burning velocities of steady one-dimensional, planar,adiabatic flames with two reactants and irreversible one-step reaction are systematically compared to results obtained by activation-energy asymptotics. In particular. hydrogen/air and methane/air flames are considered over a wide range of stoichiometries. For these flames the accuracy of the asymptotic solution in the first and second approximation is determined explicitly as a function of the Zel'dovich number and of the equivalence ratio.
