Abstract
A series of sixteen trials, seven with neat DMSO and six with 80% DMSO and 20% water to reduce the freezing point temperature, and three with polyvinyl alcohol added to the latter solution to thicken the solution to a zero-shear viscosity of seven poise were conducted on prairie terrain. Explosive dissemination was used on all trials. Vapour sampling and drop sizing results were obtained. The persistence of DMSO and 80/20 DMSO/water on prairie terrain was found directly proportional to the mass median diameter of the drops and the recovery rate of the vapour from prairie terrain agrees favourably with the predictions of an existing DRES mathematical model.
