Studies of ignition and combustion wave propagation in exothermic ceramic systems using high-speed photography
High-speed photography is a useful diagnostic tool for studying the propagation of adiabatic combustion waves in highly exothermic solid state chemical systems. Temperatures on the order of 1500 to 4000/sup 0/C can be achieved within the combustion wave front as it traverses the solid chemical reactants. Wave front propagation rates in such systems are typically 0.5 to 10 cm/sec. High-speed photography (framing speeds of 400-2000 frames/sec) is being used to study the structure of the combustion wave, obtain quantitative combustion wave propagation rates, and to study the details of ignition of the combustion wave using 150 watt HF/DF laser radiation. Examples of photographic experiments as well as examples of the chemical and physical information obtainable from these experiments are presented.
