New Approaches to Model Pyrotechnic Reactions

Stefan Kelzenberg, Norbert Eisenreich and Volker Weiser

Abstract: In most cases pyrotechnic mixtures are constituted from granular components. A theoretical study of such a granular system describes the temperature and concentration evolution in the energetic material by using hot spots as source terms for temperature and particles. The progress of the reaction is mainly influenced by particle properties which are size, melting and evaporation, gasification and surface reactions. In a first step the influence of the particle size ratio between fuel and oxidizer particles is investigated.

Keywords: hot-spot model, combustion, ignition, pyrotechnics, Green’s method
