Model of aluminum agglomerate evolution in combustion products of solid rocket propellant

A mathematical model was developed for agglomerate evolution in the combustion products of solid rocket propellant. The model is based on the principle of dividing the complex process into relatively simple phenomena with sequential synthesis of their descriptions. The model includes description of many processes observed experimentally. They are 1) metal combustion, 2) chemical interaction between metal and oxide in agglomerates, 3) change in structure of agglomerates, and 4) interaction of agglomerates and carrier flow. Quite high quality of the model was proved by satisfactory agreement between calculation results and experimental data.
