CFD ANALYSIS OF POLLUTION DISPERSION IN COMPLEX DOMAIN

Over past few decades many CFD studies and model studies has been done to analyze the pollution dispersion in urban area. CFD simulation for pollution dispersion is gaining popularity because of increased computational capability. Two-dimensional simulation of pollution dispersion has been carried out in the present study. The computational domain is a two dimensional hill and a building in its downwind direction. The detailed study of different shapes of building and hills, effect of distance between hill and building are done. The attempt is made here to find the optimum distance from pollutant source so that building will face minimum level of pollution Air quality is the major concern in the urban area. Urban areas are facing the severe problem of health issues and premature deaths due to increased level of pollutants because of traffic and industrial activities. Increasing number of industries and vehicles in urban area deteriorate the quality of air continuously.
