✦ Synopsis

Combustion transfer between gasless pyrotechnics has been studied experimentally and using a simple numerical model of combustion propagation. Implementation of the model requires a knowledge of the thermal and kinetic properties. The kinetic scheme incorporates an Arrhenius temperature dependence that determines the rate of reaction at low temperatures and a diffusion term that controls the high-temperature combustion behavior. A comparison between the conditions predicted for failure of combustion transfer and those determined experimentally offers some confirmation of the validity of the theoretical approach.
