The attack scenario of interest to Eglin involves a conventional fragmenting munition that enters a fixed above-ground or hardened underground structure and explosively detonates. As a result of weapon detonation, liquid chemical or dry biological agent is released inside the structure, either as a spill or as an airborne dispersion. The subsequent mixing with air and with explosive products brings about chemical changes in the agent. The chemical changes can include combustion with air or pyrolytic decomposition. The potential harm to civilian populations near these facilities due to building damage is largely unknown due to the inability to model the results of various attack scenarios. Current predictive methodologies are semi-empirical and do not address liquid chemical/biological (CB) agents nor do they allow for the treatment of dry compounds. A useful analytical tool for safety engineers, structural engineers, and military planners would be a theoretical physics-based model to predict the CB agent release, venting, atmospheric entrainment, and agent decomposition brought about by the combustion of these agents (i.e., the fate of the agent). ENSCO proposes to evaluate the S-Cubed Multi-Chamber BLowdown Model (MBLM) and recommend model constructs to meet the needs of Eglin AFB.
