Abstract
A novel approach is described that determines the thermal behavior and decomposition of multiphase solid and liquid substances, such as chemical wastes, fuels, aerosol particles, and propellants through rapid and controlled heating with laser radiation. The laser-driven thermal reactor (LDTR) was developed to provide near temporally resolved determination of substance thermophysical properties and chemical reaction characteristics over a wide range of temperatures (up to 2000 K), heating rates (up to several hundreds degree per second), gas pressures, and ambient environments. Described is the experimental arrangement and supporting theory that is required for determining substance thermophysical and chemical behavior, as well as results for stimulant organic chemical waste PAS 94, nitromethane, and activated carbon to demonstrate some of the technique capabilities.Citation
