Abstract
A theoretical analysis is presented of the heterogeneous opposed flow diffusion flame (HOFD). In such a system a gaseous reactant (G) impinges on a solid reactant (S) undergoining sublimation (or vaporization) and a diffusion flame is established at the stagnation point. With increasing mass flux of the gaseous reactant (mG) the mass flux of solid reactant (mS) grows until the total consumption rate of reactants reaches a limiting value due to limitations imposed by the kinetics of reaction. The analysis of the axi-symmetrical stagnation point flow with chemical reaction allows evaluation of the kinetics of chemical reaction at temperatures of interest to combustion processes. The theoretical development is applied to the solid polymers in an oxidizing atmosphere.
