Numerical Simulation of the Combustion of Aluminum Shock-Dispersed-Fuel Charges

For many explosives, only a fraction of the chemical energy is released in the detonation. Calorimetry data for TNT from Ornellas (1984) shows that when the ambient gas is inert, there is substantially less total energy released than when the ambient gas is air. This data indicates that burning of the explosion byproducts plays a key role in the overall energetics of the system. In this paper, we briefly discuss the models and the numerical methods used for the simulations and present the computational results. We also discuss future directions our work on the development of SDF explosives
