Modeling Of Air Pollutant Dispersion And Analysis

This work has been carried out to develop a three dimensional modeling program for pollutant rndispersion. The program solves partial differential equation by integrating into one mathematical rnequation and then various data are taken from literature s and primary sources for verification of the rnprogram. rn rnThe effects of meteorological and stack parameters on dispersion of pollutants ,like wind velocity, rnambient air temperature, atmospheric stability, exit temperature, velocity ,concentration and stack rnheight were studied and considered in the program. Several illustrations for reducing maximum rnground level concentration using the program are given. The output results from the program are rnpresented in different forms. rn rnDifferent simulation runs and observations were made that clearly illustrate the utility of the rnprogram in helping decision makers about air pollution control and effects of different variables in rnpollution.
