The Mechanism and Dynamics of Explosive Combustion in Aerosol Fuels
Abstract
Our initial experiments explored the mechanism of vaporization/ionization in liquid and nitrobenzene aerosols using CO2 laser evaporation and 193 run excimer laser ionization. Those experiments were critical in characterizing the capabilities of our apparatus and in laying the framework for the behavior of non-reactive species in our two-laser design. The use of multi-photon ionization schemes with the excimer laser resulted in highly fragmented mass spectra, making the identification of reaction products difficult. Therefore, in preparation for studies of more reactive, high-energy materials, we developed a vacuum-ultraviolet (VUV) laser, which ionizes molecules with very little fragmentation. We developed the VUV laser using funds from this grant. The VUV ionization technique makes our approach quite flexible and powerful in the elucidation of reaction mechanisms.
