NUMERICAL ANALYSIS OF THE INDUSTRIAL POLLUTANTS DISPERSION IN URBAN AREA

The concentration of pollutants in the atmosphere is constantly increasing every day which affects human population, as well as complete ecosystem. Present work utilizes Computational Fluid Dynamics based on the control volume to analyse influence of meteorological conditions on the dispersion of pollutants from stationary industrial sources in populated areas. Measured emission values from the Thermal Power Plant Sisak and INA Sisak Refinery were used as input data together with the boundary wind conditions taken from the meteorological model. The computational domain covers the area of the City of Sisak and the time horizon encompass period of 24 hours, i.e. one characteristic day. Simulation results demonstrate spatial evolution of pollutant dispersion for the SO2 emissions along the domain height. It was concluded that the legally prescribed emission limit value for SO2 in the populated part of the city is not exceeded during the simulation period, making the air quality satisfactory.
