Investigation of Laser-Induced Fluorescence Detection of Boron Oxides in Flames
Abstract
The purpose of this project was to demonstrate the feasibility of a laser-induced fluorescence (LIF) technique for determining the concentration of boron compounds in an atmospheric-pressure, boron seeded flame. Such a demonstration would provide a useful tool to investigate the detailed combustion chemistry of boron fuels. The two radical species which are thought to be the most important reaction intermediates in the boron combustion process, BO and BO2, were sought. A tunable pulsed dye laser which was pumped by an excimer laser was used to match the absorption bands of BO and BO2. Although a rather extensive search for LIF signal of BO was conducted, no LIF signal attributable to BO was detected. The most possible reason for this negative results was thought to be a heavy quenching under a high-pressure environment.
