A new mathematical model of pollutant dispersion near a building
- National Oceanic and Atmospheric Administration, Research Triangle Park, NC (United States)
Regulatory models of air pollution in the USA usually account for building effects using a Gaussian description of the pollutant distribution with enhanced vertical and horizontal dispersion coefficients to incorporate the influence of turbulence near clusters of buildings. On the local scale, however, buildings cause dramatic distortions of the mean flow field. These effects are not so important for the description of pollutant distributions from sources located far from buildings, because of the uniformity of the concentration fields. But for sources and receptors located in the vicinity of the buildings, an evaluation of pollutant concentration fields is necessary as a basis for designing of industrial ventilation systems and decision making to protect the environment.
