Theoretical Studies of Diffusion Flame Structures,
Abstract
Two problems concerning diffusion flames characterized by a coordinate-dependent Damkohler number were studied theoretically, namely the structure of diffusion flames in laminar boundary layers and the one-dimensional unsteady ignition of solid fuels. The model selected for the study of the structure of diffusion flames in laminar boundary layers consists of an oxidant-containing flow over a wedge of condensed fuel. The fuel was assumed to undergo equilibrium vaporization and the chemical reaction was represented by Arrhenius kinetics of arbitrary order. The near-equilibrium regime was analyzed by the method of matched asymptotic expansions. The model for the study of the unsteady ignition of solid fuels consisted of a solid fuel suddenly exposed to hot oxidizing gas. The chemical reaction was represented by second-order Arrhenius kinetics. (Modified author abstract)
