Resumo

Analytical solutions of equations are of fundamental importance in understanding and describing physical phenomena. In this work we present the solution of the two-dimensional advection-diffusion equation in Cartesian geometry by the GILTT approach, considering that the eddy diffusivity and the vertical wind profile depends on the z variable. To carry more information of the original problem, a Sturm-Liouville problem given by Bessel functions is used as basis in the solution. Numerical simulations and comparisons with experimental data are presented.
