Resumen
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. 39 Special Issue 799 804 Appadu, A.R., Numerical solution of the 1D advection-diffusion equation using standard and nonstandard finite difference schemes (2013) Journal of Applied Mathematics, p. 14. , Article ID 734374 Dourado, H., Santos, J., Reis, N., Jr., Melo, A.M.V., The effects of atmospheric turbulence on peak-to-mean concentration ratio and its consequence on the odour impact assessment using dispersion models (2012) Chemical Engineering Transactions, (30), pp. 163-168 Gousseau, P., Blocken, B., Van Heijst, G.J.F., CFD simulation of pollutant dispersion around isolated buildings: On the role of convective and turbulent mass fluxes in the prediction accuracy (2011) Journal of Hazardous Materials, 194, pp. 422-434 Jaiswal, D.K., Kumar, A., Kumar, N., Yadav, R.R., Analytical solutions for temporally and spatially dependent solute dispersion of pulse type input concentration in one-dimensional semi-infinite media (2009) Journal of Hydro-Environment Research, 2 (4), pp. 254-263 Kaabeche, K., Belbaki, A., Coupling effect of non-linearity and chemical heterogeneity on reactive solute transport in a fixed bed (2013) Chemical Engineering Transactions, 32, pp. 1549-1554 Lauret, P., Heymes, F., Aprin, L., Johannet, A., Dussere, G., Lapebie, E., Osmont, A., Atmospheric turbulent dispersion modelling methods using machine learning tools (2014) Chemical Engineering Transactions, 36, pp. 517-522 Lora, E.E.S., (2002) Prevention and Control of Pollution on the Energy, Industrial and Transport Sectors, p. 862. , 2nd Edition, Intercincia (in Portuguese) Potter, M.C., Wiggert, D.C., Hondzo, M., Shih, T.I.P., (2004) Fluid Mechanics, p. 688. , Cengage Learning, So Paulo, Brazil (in Portuguese) Savovic, S., Djordjevich, A., Finite difference solution of the one-dimensional advection-diffusion equation with variable coefficients in semi-infinite media (2012) International Journal of Heat and Mass Transfer, 55, pp. 4291-4294 Singh, M.K., Ahamad, S., Singh, V.P., Analytical solution for one-dimensional solute dispersion with time-dependent source concentration along uniform groundwater flow in a homogeneous porous formation (2012) Journal of Engineering Mechanics, 138 (8), pp. 1045-1056 Mazaheri, M., Samani, J.M.V., Samani, H.M.V., Analytical solution to one-dimensional advection-diffusion equation with several point sources through arbitrary time-dependent emission rate patterns (2013) Journal of Agricultural Science and Technology, 15, pp. 1231-1245 Modenesi, K., Furlan, L.T., Tomaz, E., Guirardello, R., Nnez, J.R., A CFD model for pollutant dispersion in rivers (2004) Brazilian Journal of Chemical Engineering, 21, pp. 557-568 (2012) Wolfram Research Inc, , Mathematica 9.0, Champaign, Illinois, USA
