Texto completo da fontePyrotechnic compositions are composite energetic materials whose combustion produces various effects such as light, smoke, sound, or heat. This diversity makes them highly versatile, allowing for multiple applications in both civilian and military contexts. Composed of a granular mixture of at least one oxidizer and one reducer, their combustion characteristics can be modified by numerous factors: the nature and composition of the mixture, particle size, compaction rate, and manufacturing method. Each of these parameters influences the structuring of the composition by generating local variations in reactant concentration, which can be more or less favorable to the propagation of combustion. This thesis aims to develop a numerical model that incorporates the effect of anisotropy using image processing techniques.Following a brief review of the state of the art on pyrotechnic compositions, the development of a model differentiating between oxidizer and reducer grains is presented. This model incorporates two reactions coupled with mass transport phenomena: the oxidizer decomposes, releasing oxygen that diffuses within the material before reacting with the reducer. A parametric study helped identify two distinct regimes, characterized by the Damköhler number. Finally, compositions in the form of pellets were manufactured and characterized. Scanning electron microscopy (SEM) images of their surfaces were used to develop 2D maps of the distribution of the constituents using image processing techniques. These maps were then used to initialize the concentrations in the model's computational domains. Their thermal diffusivity was calculated numerically and compared to experimental measurements. Combustion simulations highlighted the impact of the local grain distribution on the propagation of the combustion front
