Development of model for measuring direction and transportation of urban air emission

Abstract

This research has designed a unique method of simulating the movement of air pollutants with respect to winds direction in urban areas. A good study of variable and invariable parameters for the factors of air emissions in urban area has assisted in conceptualization of major forces and factors that are responsible for the dispersion of air pollution in urban areas. These parameters have been used in the design, development and simulation of this model. New findings include, establishment of method for tracing the direction of air emissions in urban areas using trigonometric and vector analysis. The model was designed on the basis of variable and invariable parameters for the factors influencing air pollution in urban areas. Good choice of constraints was made. The Model has quantitatively established the mathematical and physical relationship between the air concentration and deposition values of one or more pollution species in space and time. It uses atmospheric, and meteorological variables and parameters, to describe removal and transfonnation processes in urban areas. The fimdamental approach and empirical analysis of various factors governing the distribution of the air pollutants in urban areas gave new results and findings. Results are discussed.
