abstract
2017 by Waruna Kulatilaka. The first step of developing counter-WMDs for chemical weapons such as sarin gas, involves detailed understanding of the combustion chemistry and chemical kinetics of a sarin surrogate such as triethyl phosphate. Studying these WMD surrogates allows for the ability to refine these techniques before the addition of inhibiting chemicals to real mixture. In this study, mixtures of triethyl-phosphate (a sarin gas surrogate) are studied and compared to pure hydrogen combustion. In order to better understand the combustion chemistry, this study focuses upon the spectroscopic characterization of time-resolved emissions within the flame. The addition of triethyl-phosphate to hydrogen mixtures is found to increase the overall intensity of the spectra obtained, even to the point of saturation of the spectrometer in some cases. The results of these spectroscopic studies are useful for designing better time-resolved spectroscopic experiments as well as 2D imaging of selected flame front emission species.
