Photochemical Enhancement of Combustion and Mixing Its Supersonic Flows

Abstract

Initiation and combustion enhancement of gaseous (vaporized or atomized) fuel-air mixtures can be produced photochemically by ultraviolet irradiation in both stationary and flowing mixtures. This report presents a summary of the observed combustion effects and the intrinsic wavelength effects related to the photochemical combustion initiation and enhancement principle. Specific in-depth attention is given to radiant penetration into the reactant mixture, the possible use of laser sources and the role of the electronically excited oxygen atom in the photochemical processes. Analytical description of the phenomena provides correlation of the experimental results and extension of the findings to other conditions not directly observed by experiment.
