In the paper a general mathematical description of the flow in the internal chamber of solid rocket motors is presented. The formulation adopted take into account the multi-species and multiphase, reactive, multidimensional characteristics of the flow. The grain combustion is described by a pressure dependent law; aluminum droplet are modelled by a Lagrangian approach, coupled with the Eulerian formulation adopted for the gas phase. The mathematical model has been implemented in a simulation code and several simulations have been performed; in particular in the paper the results for two geometries are described: a simple cylindrical port-area rocket and the Zefiro 9 SRM.
