Modes of gasless combustion and macrostructure of combustion Front (for the Ti-Si system as an example)

Résumé

Gasless combustion of Ti+Si mixtures (taken as an example) was investigated by high-speed video recording followed by computer-assisted processing of stored still frames. The three-dimensional shape of the combustion front was reconstructed, and explanations were proposed for the combustion front propagation modes along the surface of cylindrical samples. The reconstructed front configuration was found to be nearly paraboloidal. The modes of unsteady combustion in T-rich and Si-rich mixtures turned out to be strongly different. The results were used to rationalize the available experimental data on unsteady combustion in terms of microheterogeneous theory.
