Abstract:
The mathematical modeling of ignition processes for heterogeneous systems under nonstationary heat- and mass-exchange is performed with regard for the two-stage thermal degradation of oxidizer and fuel binder the heterogeneous oxidation of fuel around AP grains, the integral heat release in gas-phase reactions through the effective heights of individual flames, as well as the effect of the products of thermal decomposition on radiative and convective heat- and mass-exchange with the environment. The model is applied to a model composite system PMMA+AP.
