Numercal Model for Airpollutnt Emitted from an Area and Point Source in an Urban Area with Chemical Reaction and Removal Mechanisms

Abstract

An inclusive numerical mathematical model of primary pollutants is presented. This model allows the estimation of the pollutants dispersionradiated from area and point source in city region. Theeddy diffusivity and realistic wind velocity profiles are taken in current model. The intricate problem is simplified numerically with Crank-Nicolson finite difference technique. In stable and neutral atmospheric conditions pollutant concentration is maximum on the boundary of point sourceand as well asat bottom surface.
