Modeling kinetics for the reaction of aluminum and teflon and the simulation of its energetic flow motion

Abstract

Simulations with reduced kinetic models are used to study shock ignition and detonation in reactive materials that may support non-classical detonation. Porous aluminum Teflon oxidizer mixtures that support combustion reactions in air are considered, as a member of a class of materials with intrinsic interest. We recast a phenomenological theory [4] with realistic kinetics with end products whose primary components are AlF 3, CO, CO 2 and Al 2O 3. Intermediate products include at least thirty elementary reactions; a sub-set can be selected to simplify, but a hard problem remains. Results of the multi-species evolution and its impact on rapid self-oxidizing combustion and possible detonation conditions and the computational methods are presented. © 2012 American Institute of Physics.
