Abstract

India has experienced a high rate of Urbanization, higher density of population in cities has more of it. The higher population Density with cities like Mumbai having population densities of 20680 person/km has led to crowded space in a urban setting decreased Natural Ventilation of Air Pollutants. Using the advanced Computational and Mathematical models pollutant concentrations are estimated. Street Canyon models, which may include simplified photochemistry and particle deposition-suspension algorithms. These models when used in a knowledgeable way principles that govern the dispersion and transformation of atmospheric pollutants. A study of vehicle exhaust dispersion within different street canyons models in urban ventilated by cross-wind is conducted at this work to investigate how air pollutant dispersion is exaggerated by wind speed, building height to width ratios, street and building geometries and canyon street number.
