RESULTS OF MODEL EXPERIMENTS ON THE PROPAGATION OF A SETTLING ADMIXTURE IN THE LOWER LAYER OF THE ATMOSPHERE UNDER VARIOUS METEOROLOGICAL CONDITIONS,
Abstract
Further study and observation are needed to measure and calculate more scientifically the dispersal of gasses and smoke emanating from chimneys and carried by air currents. The Institute of Applied Geophysics used a 300 meter meteorological tower. Various heights of source were used and sticky surface plane tables were deployed in a radius of 10-20 km around the tower. Particles dispersed from a chimney source are carried by the wind and settle under influence of their weight. Information obtained thus far has been insufficient to permit deriving a formula for practical calculation of chimney heights for newly constructed enterprises and to determine the area of contamination. In the experiments, a polymethyl-methacrylate powder consisting of particles 10-100 microns in size was used as the contaminant. Tests were conducted under a variety of meteorological conditions both in summer and winter and during day and night. The effect of temperature inversions was found to have a significant effect on dispersal. (Author)
