Project Foggy Cloud VI:Design and Evaluation of Warm-Fog Dispersal Techniques.

摘要

The Naval Weapons Center, working in collaboration with various activities listed herein, conducted a series of warm-fog modification experiments under Project Foggy Cloud VI. Electrostatically-charged droplets dispensed from aircraft to induce fog droplet coalescence and rainout, and electrostatically-charged bubbles dispensed from the surface to collect and precipitate fog droplets were techniques tested at the Arcata-Eureka Airport in northern California. The spreading and maintenance of monomolecular films on the water surface to suppress evaporation and inhibit fog formation was the basis for testing in the Panama Canal. Results from tests employing the airborne electrical charging system, while initially inconsistent, gave evidence of increasing positive effects as system modification was accomplished in the field. Charged bubble experiments, while theoretically sound, presented problems with regard to bubble production and buoyancy as well as targeting. With the airborne electrical charging system in a more advanced state of design and giving promise for a more immediate fog dispersal system, the charged bubble concept should be relegated to engineering improvement until the airborne system is finalized.
