Abstract
Some of the more recent results of studies involving the use of
hygroscopic materials and ionic surfactants as warm fog dispersants
are covered in a brief survey of the literature. The fog chamber, equipment and experimental procedures used in this study are described in
detail. Seeding agents utilized during these small-scale fog chamber
experiments were limited to the use of hygroscopic materials, surfactants
and ethyl alcohol. Results indicated that those hygroscopic
agents tested, such as NaCl and glycerin, proved to be relatively
effective warm fog dispersants compared to distilled water. The ionic
and nonionic surfactants tested dissipated warm fog at approximately
the same rate as distilled water and were considered ineffective.
Ethyl alcohol appeared to initially increase the fog intensity, and
thus, retard fog dissipation. Conductivity/Resistivity measurements
and illustrations of the relative droplet sizes and shapes of the
various agents used are also contained in this report. The effects
on plants of four of the hygroscopic agents are also discussed and
illustrated.
