Modeling of convective mode combustion through granulated propellant to predict detonation transition

An analysis of the transient reactive flow through highly loaded but mobile particles of solid propeliant is presented in order to determine whether the high-speed flame front can provide a pressure wave that can interact with the flow to build up to a condition of detonation. Discussions are presented which deal with the various forms of the field balance conservation equations, as well as the significant number of additional constitutive relations required to model this flow. Results are presented which indicate the sensitivity of the most important parameters on the unsteady flame-spreading rate. Possible criteria for DOT (deflagration-to-detonation transition) are presented.
