Abstract: The aim of this work is to evaluate the pollutants concentration considering a transient three-dimensional model, non-local turbulence closure and the computational time to simulate the pollutants dispersion considering different methodologies to solve the linear system that is obtained by applying the 3D-GILTT method in the three-dimensional advection-diffusion equation. To validate the model, unstable tank experiment data were considered. The results show that the Gauss-Seidel method has the shortest computational time to simulate the pollutant dispersion and the model satisfactorily simulates the observed concentrations, considering and not considering the non-local turbulence closure term.
