Fundamental Description of the Simulation Technique for Air Pollution Computational Model

Abstract

In this report, we explain the way of guidance of the diffusion equation which describes diffusion phenomena. We also show the approach method from the finite difference approximation in order to understand it if possible. Next, a simple diffusion program and a program of the convective diffusion equation are shown according to the Fortran Language. Finally, it close to the analysis of actual phenomenon by showing a example of the three-dimensional convective diffusion equation.
