ON THE EXTINCTION OF OPPOSED-JET DIFFUSION FLAMES: A PHYSICAL CRITERION FOR EXTINCTION,
Abstract
A physical criterion for the extinction of opposed-jet diffusion flames is presented. This criterion, when used in conjunction with the Spalding Theory of mixing in opposed-gas jets, enables the apparent flame strength to be related to (1) the effective maximum chemical reaction rate in the opposed-jet flame, and (2) the laminar flame speed of an equivalent pre-mixed diffusion flame. The derived relationships differ somewhat from similar relationships given by Spalding's earlier theoretical treatment of the phenomena in the thin-flame approximation, but do yield quantitatively similar results when compared with experimental data reported for opposed-jet diffusion flames involving oxidation of simple hydrocarbons and ammonia.
