The Effect of Pressure Transients in Diffusion Flames.
Abstract
As an illustration of the effects of pressure transients on the ignition and subsequent evolution of diffusion flames, an analysis is presented of the mixing and simultaneous reactions between to semispaces of reactants subject to an arbitrary pressure transient. The chemical reaction is described in terms of an overall Arrhenius reaction with an activation energy large compared with the thermal energy in the mixing layer. After an initial inert mixing stage, there is a short ignition stage resulting in chemical equilibrium with complete consumption of one of the reactants in one plane in the mixing layer. One or two premixed flames originate at the ignition plane moving across the mixing layer, and thus establish a diffusion controlled mode of burning.
