Time dependent model for chemically reactive pollutants emitted from various line sources into a stable atmospheric boundary layer

Abstract

Moka Shekhu and C. Sulochana

An analytical model for dispersion and diffusion of chemically reactive primary pollutants emitted from an elevated line sources into a stable atmospheric boundary layer with generalized wind velocity of quadratic function of vertical height z. The model obtained from an analytical solution of the atmospheric diffusion equation with the quadratic diffusion coefficient (exchange coefficient) and three different types’ sources viz. continuous, an instantaneous and step-function type sources. The pollutants considered to be of chemically reactive primary pollutants emitted from the above said sources. The results are validated with that of the case where there is particular type of wind profile and have good agreement with them. In order to facilitate the application of the model the results for the general situation that includes chemical reaction rate and time dependent source incorporated in the model.
