Download or read book Thermal and Chemical Fog Dissipation written by Bruce A. Kunkel and published by . This book was released on 1973 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of thermal and chemical fog dispersal tests, conducted by AFCRL during July 1972, are presented and discussed. Forty-three tests were conducted in fog, thirty-three of which were suitable for analysis. Ninety-six additional heat tests were conducted in clear air. Two wide-area urea seeding tests were also performed. An instrumented 200-ft tower, a lidar, and a ground network of visibility sensors and droplet sampler were used to monitor the effects of the tests on the foggy environment. The seeding tests were unsuccessful. Improper execution of the wide-area seeding pattern due to a lack of knowledge of the winds at the seeding location was responsible for the failure of the seeding tests. (Modified author abstract).

Download or read book The Air Quality and Noise Impact of a Warm Fog Dispersal System Using Momentum Driven Heat Sources written by Bruce A. Kunkel and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of a Warm Fog Dispersal System (WFDS) on the air quality and noise level is assessed. The WFDS, designed by AFGL, uses various combinations of heat and thrust to disperse the fog over the runway and approach zones. Emission and noise levels that are within the state-of-the-art are used in this assessment. Calculations show that within the cleared area the pollution concentrations, on the average, are within the EPA standards. (Author).

Download or read book Interaction of a Buoyant Turbulent Round Jet with a Co flowing Wind written by Milton M. Klein and published by . This book was released on 1975 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A broad effort is being conducted to develop an operational Warm Fog Dispersal System (WFDS) using ground-based heat sources. In order to determine the optimum heat and thrust for the combustors in the WFDS, investigations have been made of the buoyant motion in round- and plane-heated turbulent jets in co-flowing (that is, same direction) wind fields. This report describes a method of calculating the round jet case. The method can be used for jet velocities of 100m/sec or less, wind velocities below or equal to the jet velocity, and jet temperatures up to 3 times the ambient value. Initial jet velocities of 5 and 20m/sec and temperature excesses, relative to the ambient temperature, of .3 and 1 were selected for the calculations.

This book was released on 2017-01-28 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the history of marine fog research and applications, and discusses the physical processes leading to fog's formation, evolution, and dissipation. A special emphasis is on the challenges and advancements of fog observation and modeling as well as on efforts toward operational fog forecasting and linkages and feedbacks between marine fog and the environment.
