Diffusion of Stack Gases in Very Stable Atmospheres,s over fairly flat terrain. Photographs of oil-fog plumes taken at the Brookhaven National Laboratory are presented to show the non-isotropic character of diffusion during conditions of strong stability..Since relatively rapid dilution occurs within the first few meters of a stack, the diffusion pro

The Statistical Theory of Diffusion by Turbulent Eddies,ies of the irregular random motions and fluctuations that occur in a turbulent fluid. The diffusion of particles is known to depend upon the Lagrangian correlation coefficient . defined as the correlation between the velocity of a fluid particle at any instant and that of the same particle after a t

Instruments for Air Pollution Measurement,of the pollution effect. Pollution by particles presents a special problem: a knowledge of the range of particle sizes composing it, in addition to the mass concentration, is required to assess the significance of the pollution; the soiling effect of the pollutant should also be determined. The poss

Ground-Level Measurements of oil-fog Emitted from a Hundred-Meter Chimney,e by means of an oil-fog test effluent. Measurements of oil-fog concentrations at ground-level have been made during a wide variety of meteorological conditions. The data accumulated in the first forty-six tests are summarized in this paper, together with pertinent meteorological information. A brie
