Abstract : Neutralization of Chemical/Biological (CB) agents via entrainment into flames/hot spots, ignition/combustion by blast waves, dispersion of particles/droplets, and venting and plume formation from the damaged structure are all highly transient phenomena with a wide range of characteristic time and length scales. Geometry of the target structure can also introduce unsteady flow complexities, such as re-circulating flow behind obstacles and in corners that can a ect mixing and combustion processes. The dynamics of the Agent Defeat (AD) scenario encompasses a wide range of scales: the molecular scale (at which species mix and react), the nano-scale (at which nucleation, surface growth and chemistry, and Brownian aggregation occurs), the micron scale (at which shear-induced aggregation, unsteady shear flows, shock or detonation structure, coagulation, breakup, vaporization, and small-scale mixing occurs), the macro-scale (at which large-scale turbulent mixing and transport occurs), and macro scale (at which geometrical constraints of the problem manifest).
