Dissemination of Solid and Liquid BW Agents

Abstract

Progress is reported on an experimental study of the effect of exposure to heated air streams on the viability of Sm aerosols. Results from experiments on the characteristics of powders are presented including investigations of frictional forces between powders and channel walls and dynamic angle of repose of Sm powder. Theoretical studies of load transmission in particulate materials and several specific cases of force transmission were analyzed. The properties of slurries, which include the thermal properties of egg slurry samples, were determined. Investigations were also made of the properties of slurries of Sm in a fluorochemical liquid. Wind tunnel investigations of the use of slip stream energy to deagglomerate finely divided solid materials progressed. Experimental results on the performance of a high velocity sampling probe and of an analysis of the influence of the effective agent filling density on the aerodynamic drag of solid agent disseminating stores are presented.
