A THEORY OF FLAME PROPAGATION IN SYSTEMS WITH BRANCHED CHAIN REACTIONS

Abstract

A theory is presented on flame propagation in systems with branched chain reactions represented by a model reaction with an active center of one type. This problem is solved by calculating the initiation rate, chain propagation rate, chain branching rate, and the second order chain termination rate. A solution of the problem of flame propagati n in a system with a branched chain reaction with three active centers is also presented. The combustion of hydrogen was taken as an example of this reaction. A system of thermal conductivity equations and three diffusion equations of hydroxyl, of a hydrogen atom, and an oxygen atom is examined without taking into consideration the second order chain termination.
