Numerical Investigation of Aluminum Burning Behind Blast Waves
Abstract
Energy release by aluminum burning behind the blast wave front produced by heavily aluminized explosives was investigated. An aluminum evaporation/reaction model within the multi-phase flow was applied. The modeled HE includes a significant percentage of aluminum particles, whose long-time afterburning and energy release must be considered. As a first step in the overall 3-D comprehensive methodology development, the evaporation of small aluminum particles, with 5, 50, and 500 m diameter, was investigated in a 1-D code. The aluminum particles can react with oxygen, water, and carbon dioxide. The resulting pressure profiles are different from those obtained for the no-reaction case or using a one-reaction which only consider the reaction with oxygen. Finally this aluminum burning model was incorporated into our in-house 3-D code, FEFLO.
