Abstract

This research effort addresses modeling of the transportation of air pollution in the atmosphere and the numerical analysis of the partial differential equations used in such modeling. Three Gaussian models are examined and compared using example problems. Several finite difference schemes are developed to solve the partial differential equations used in air pollution transport modeling. This study examines three Gaussian models SCREEN, AFTOX, and the program GAUSPLUM. The model GAUSPLUM is developed in this study and uses the Ada programming language and the analytic solution to the advection- diffusion equation. Numerical analysis of the partial differential equations PDE used in air pollution modeling is also examined. The equations are generally parabolic or hyperbolic PDEs. The following are examined in this research the advection equation the one-, two-, and three-dimensional advection-diffusion equations and the two-dimensional steady-state equation.
