Some Phenomenological Aspects of Heterogeneous Combustion of Condensed Systems

The combustion process of heterogeneous condensed systems (HCS) is a complex phenomenon characterized by some peculiarities: Phase transitions in the combustion wave, time and space inhomogeneity of the temperature and burning rate, agglomeration and dispersion of the condensed phase, concentration limits, etc. The order and completeness of chemical reactions in a HCS combustion wave depend not only on the energetic parameters but on the composite structure as well (porosity, component particle size and shape, etc.). Some phenomenological aspects of the HCS combustion process are analyzed. Peculiarities of metal particle agglomeration and its influence on the metal oxide size are discussed. The high‐temperature kinetics of Al+Al₂O₃ interaction are shown. The complexity of the analyzed phenomenon calls for a non‐traditional approach and technique.
