Demonstration of a new method for dispersing warm fogsLow visibility due to warm fog has caused costly disruptions in the case of aircraft schedules, and fog-related difficulties can arise in connection with Space Shuttle flights. As current methods of fog elimination are not entirely satisfactory, Kelley (1983) has proposed a new brute force procedure for warm fog dispersal. This procedure makes use of recycled water sprays. Fog droplets are removed by coalescence/rainout. Details regarding the involved approaches are described, and a demonstration of the method is discussed. Attention is given to tests conducted in October 1984, visual range improvement in response of water spray fog dispersal, a systematic investigation concerning a selection of firefighting nozzles, and histograms of fog droplet number concentration measured in the spray curtain outflow with a forward scattering spectrometer probe.
