Optical and Fluid Dynamic Properties of Explosion - Produced Dust Clouds.

Abstract

A model (DIRTRAN) descriptive of time/space dependent optical properties of explosion-generated dust clouds has been developed. This model includes three components: a dust source term, atmospheric diffusion, and optical transmission. Data analysis indicates that for a given soil, the greatest uncertainties lie in the determination of soil comminution/agglomeration under the dynamic loading produced by explosions. When an empirical parameter descriptive of this effect is employed, the model predicts cloud optical properties which compare favorably with experiments under a variety of explosion patterns, charge types, and atmospheric conditions. A computer code (DIRTRAN-I) which embodies this model has been delivered to the Army Atmospheric Sciences Laboratory for inclusion in the Electro-Optics Systems Atmospheric Effects Library. (Author)
