Studies of ignition and combustion wave propagation in exothermic systems using high-speed photography. [Combustion synthesis of ceramics]
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/s. High-speed photography (framing speeds of 400 to 2000 frames/s) is being used in our laboratory 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. This paper presents examples of photographic experiments as well as examples of the chemical and physical information obtainable from these experiments.
