Modélisation et simulation numérique d'un écoulement diphasique de la balistique intérieure

Abstract : This work is devoted to the numerical modelling and simulation of internal ballistics problems. We study two different two-phases models: the Gough's model (spread in the ballistic community) and a relaxation model. These models have different mathematical propreties but are conditionnally hyperbolic and non conservative. We propose a numerical method in order to approximation the solution of the associated system of partial differential equations in three space dimension. A part of this study is focused on the source terms modelling the powder ignition and combustion at low pressure.
