Pereira M., Pozza S., Timóteo V., 2014, Numerical Methods for the Evaluation of Pollutant Dispersion Based on Advection-Diffusion Equation, Chemical Engineering Transactions, 39, 799-804.
Several pollutant dispersion models have been developed to provide subsidies for environmental impact assessment and monitoring of natural resources such as air, soil and water. In this work, we solve the one-dimensional advection-diffusion equation using an adaptive-step algorithm for the analysis of pollutant dispersion and compare it with other recent work, obtaining very similar results for two solute dispersion scenarios, one along steady flow through inhomogeneous medium and another along uniform flow through homogeneous medium. Our method is characterized by low computational time and simplicity of the code, and may contribute as a numerical background for pollutant source management.
