Propagation of Flames Supported by a Zeroeth-Order Chemical Reaction

Abstract

Flames supported by zeroeth‐order chemical reactions have two very useful unique properties. Their characteristics are independent of diffusion, and the chemical reactions are completed at a finite point in space. These properties should make zeroeth‐order flames ideally suited to serve as ``global'' reactions for complicated flame systems involving either three‐dimensional geometry or time‐dependent phenomena. Extensive tables are given for the properties of steady‐state one‐dimensional zeroeth‐order flames. Good agreement with the numerical calculations is obtained by using a simple approximation (based upon the Adams and Wilde approach) which results in simple closed‐form expressions for the flame variables.
