Simulation of Condensed Products Formation at the Surface of a Metalized Solid Propellant

This article considers mathematical simulation of a process of condensed products formation near the surface of a burning solid propellant. These products include agglomerates and smoke oxide particles (SOP). The idea of predicting properties of these products is based on classification of propellants with various combustion regularities depending on formulation factors. For these types of propellants, the developed models are used to determine (estimate) the relations between the two main fractions, size of the agglomerates and SOP, parameters of the chemical composition and structure of the agglomerates. Validity of the used approaches is confirmed by comparing the calculation results and experimental data.
