The Structure of Multiple Diffusion Flames for a Two-Step Chain Reaction,

Abstract

The low speed deflagration of initially unmixed gaseous reactants under an irreversible two-step chain reaction is examined. Both equilibrium burning, in which two separated flames of zero thickness arise, and near-equilibrium burning, in which two spatially separated flames of small but finite thickness arise, are studied by limit process expansion techniques. Two time-dependent two-dimensional flows are examined: the first is diffusion flow; and the second is counter stagnation flow. The latter flow, in which there is an impressed finite strain parallel to the flame, such that the flame, itself, is longitudinally stretched, is discussed as elucidating the characteristics of combustion in turbulent shear flows.
