We describe simulations of solid rocket motors that involve coupling between the core fluid flow, the structural response of the propellant and case and the combustion of the propellant. A predictor-corrector algorithm is employed to treat the fluid-structure interaction. The combustion rate of the propellant is coupled to the fluid flow via an empirical power law relationship. Our algorithm couples the physical processes involved using a partitioned approach, enabling us to use existing codes to perform the bulk of our simulations. We give special consideration to the jump conditions that hold at the fluid-structure-combustion interface. Results are presented that demonstrate the parallel performance of our code on a variety of architectures. A large-scale simulation is also described that demonstrates the capability of our code.
