The Mechanism and Dynamics of Explosive Combustion in Aerosol Fuels

Abstract

The research involves the production of high energy material particles with diameters between 1 and 5 microns and the study of its subsequent combustion by rapid laser heating or photolysis. Alternatively, the high-energy ionic liquids with no vapor pressure are placed on a plate inside the vacuum and irradiated with high intensity IR radiation. In either case, the reaction products are followed by single photon vacuum UV laser ionization in a time of flight (TOF) mass spectrometer. The purpose is the elucidation of reaction mechanisms in high density or condensed phases and the development of more efficient methods of combustion. The experimental set-up includes aerosol generation tools that inject the particles at atmospheric pressure into an aerodynamic lens, which focuses the particles onto the center of a 3 mm expansion nozzle, whereupon the particles are accelerated to velocities of 200 to 300 m/s depending upon their size.
