Theoretical And Experiment Analyses On Atmospheric Dispersion Of Air Pollution

The propagation and diffusion of gases pollutant creates new problems to modem society and the understanding to its behaviors is important for emission control. In this thesis, physical and mathematics air pollution models under the condition of point line and face dispersion of air pollution were established. And as to investigate the effect of relative humidity on atmospheric dispersion of air pollution, physical and mathematics air pollution models under the condition of changeful relative humidity based on the theoretic of the dispersion of complex component were also established. The numerical solutions of all the models show how the emission from and the relative humidity's change affect the air pollution's dispersion. Air tunnel tests were established to investigate the general rule of the atmospheric dispersion experimentally. The analysis of the test data that has been changed dimensionlessly shows the rules of atmospheric dispersion under different conditions such as flow field, wind and relative humidity. It shows that these models also can be used in estimating the atmospheric dispersion of air pollution.
