ON THE INTERNAL STRUCTURE OF LAMINAR DIFFUSION FLAMES

Abstract

A study was carried out on the influence of chemical kinetics on laminar diffusion flames. In most of the flames of practical interest, the reaction zone is of negligible thickness, making it possible to obtain a solution of the boundary layer type. At each side of the reaction zone the temperature and concentration distributions may be determined by using the Burke-Schumann assumption of infinitely fast reaction rate. In the reaction zone, or chemical boundary layer, the convection effects may be neglected as compared with chemical reaction, conduction and diffusion effects. The equations governing this layer take then a simple for ; and from their solution a criterium for the validity of BurkeSchumann assumption and for flame extinction may be obtained. (Author)
