RESEARCH OF AIR POLLUTION FROM TRAFFIC IN «STREET CANYONS» OF CITY

T. I. Rusakova

Abstract


Purpose. The article is devoted to state analyze of atmospheric air at its pollution with vehicle emissions in Dnipropetrovsk city, the development a numerical model and applied computing program for research of air pollution level with vehicle emissions on the streets when several buildings are located on the scheme «street canyon». Methodology. To achieve the research purpose it was studied the dynamic of change concentration of different pollutants that have been fixed on monitoring station of air quality in Dnipropetrovsk city. It was performed level assessment of air pollution from traffic (according to the Main Statistical Office in Dnipropetrovsk region). It was developed methodology for numerical calculation of concentration the atmospheric air pollution from vehicle emissions. To solve hydrodynamic task of determining velocity field of wind flow in streets the model of separated flows of an inviscid fluid was used; to solve the task of the calculation process of dispersion pollution the equation of convective-diffusion transfer of pollutant was used. To implement the proposed methodology we used implicit difference schemes. Findings.In the work a mathematical numerical model was developed and computing programs on its base were created. It allows conducting the computational experiments for evaluation the level of air pollution from vehicle emissions on the streets when several buildings are located on the scheme «street canyon». As a result of research regulations on change concentration of carbon monoxide near a considered group of buildings at different pollutant emissions were established. Originality.This numerical model was developed which allows accounting the hydrodynamic impact of group buildings on dispersion of pollutants when the wind speed and the vertical diffusion coefficient vary with height. Practical value. Conducting such class of computational experiments is necessary in the case of reconstruction of city microregions, during the planning and construction of new highways, change in the structure of traffic in the city.
