A three-phase Navier-Stlkes code (CRAFT) that has been applied to varied multi-phase combustion problems, including high explosive (HE) detonation, blast wave interactions with bulk liquid, particulate dispersion and entrainment by turbulence, etc., will be specialized to address the end-to-end CB agent neutralization scenario. This computational framework includes large eddy simulation (LES) methodology for transient turbulent simulation and multi-step decomposition/combustion of condensed (liquid and solid) phase, in additional to generalized gas phase kinetics. In Phase I, a prototype model will be demonstrated for the complete sequence of events occurring from the onset of CB container rupture to dispersion/entrainment of partially neutralized BC agent into neighboring rooms of the storage facility, and culminating in atmospheric dispersion. The requisite-coupled methodology has been derived from simulations of atmospheric dispersion of CB agents resulting from threat missile intercept. The model utility will be demonstrated by conducting simulations of varied neutralization concepts in an end-to-end mode. Assessment of modeling parameters having the dominant influence on systems parameters (toxicity concentrations, dispersion range of CB agents, etc.) will be performed, and, the steps towards developing a systems-oriented engineering model via lumped parameter simplifications to advanced Navier-Stokes methodology, will be identified.
