Mathematically modeling the transport of hazardous air pollutants from multiple sources
- Stanford Univ., CA (United States). Civil Engineering Dept.
Analytical solutions of the atmospheric diffusion equation with wind speed and eddy diffusivities expressed as power functions of height have been restricted to total reflection at the boundaries (Neumann-type boundary conditions), and limited to a single isolated point source located at the origin. In reality, however, due to partial adsorption or deposition at the earth`s surface, the actual concentrations of airborne pollutants near groundlevel most often fall between Dirichlet (total adsorption) and Neumann boundary types. In addition, multiple-source dispersion modeling is still done almost exclusively using the Gaussian plume model. It is therefore the purpose of this publication to systematically study the solutions of the atmospheric diffusion equation for several boundary condition types, and to apply the Green`s function concept to the multiple-source problem, where the sources can be located anywhere in the region of interest.
