Radiative Augmented Combustion.
Abstract
Radiative augmented combustion is based on the fact that radiation of selected wavelengths is capable of photodissociating stable molecules, combustion intermediates and other inhibiting species into reactive radicals. Subsequent increases in concentrations of these radicals can modify the overall kinetics and produce radiative ignition and combustion enhancements. The potential of this technique was previously demonstrated under static conditions. Recently, it has been also demonstrated under flow conditions, with advanced vacuum ultraviolet (VUV) and ultraviolet (UV) light sources. This program emphasizes research on the interaction between VUV/UV radiation and combustion under flow conditions. The main objective is to demonstrate proof of concept by radiatively igniting combustible mixtures at conditions where thermal ignition is unreliable. Additional objectives are to provide non-intrusive (optical) flameholding and to increase flame speed. Another important goal is to improve the fundamental understanding of the role of photochemical reactions within the whole kinetic scheme, and ultimately to identify the most effective photodissociative path. Consequently, the program is divided into two main subjects: ignition and enhancement.
