Abstract:

Neutralization of ChemicalBiological CB agents via entrainment into flameshot spots, ignitioncombustion by blast waves, dispersion of particlesdroplets, 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.
