Abstract
A new approach to the theory of burning velocity is presented in which a flame front moves forward at a rate determined by the random walk of chemical (potential) energy. The flame velocity is determined by the value of n which is a collision rate divided by a reaction rate, both determined at the point of maximum reaction velocity. The comparison between theoretical and experimental flame velocities is given for cases in which the chemical kinetics are quite well understood. Empirical activation energies for reaction are given for certain hydrocarbon flames. It is hoped that these may be useful in determining the important chemical processes in hydrocarbon flame propagation.
