In this work we present the GILTT method for the solution of the advection–diffusion equation
utilizing an eddy diffusivity depending on source distance. With this new approach, where no …

Os modelos matemáticos de dispersão de poluentes na atmosfera representam um
instrumento técnico importante, seja para o conhecimento do estado do ambiente, unidos à …

The present study proposes a steady-state mathematical model for dispersion of
contaminants in low winds that takes into account the along-wind diffusion. The solution of …

Transport and diffusion models of air pollution are based either on simple technique, such
as the Gaussian approach, or on more complex algorithms, such as the numerical solution …

An analytical technique to solve the Eulerian advection–diffusion equation for nonstationary
conditions and passive contaminant within the Planetary Boundary Layer is analysed in this …

A parameterisation for the vertical diffusivity has been recently derived by some of the
authors. The formulation, based on the Taylor's statistical theory, the Hay and Pasquill …

In this paper a time dependent semi-analytical model is discussed which overcomes the
limits of the existing analytical ones. This model is compared both with the results of a …

In this paper, we present a numerical model to study pollutant dispersion in the atmospheric
boundary layer (ABL). The model accounts for the mechanisms of advection by the mean …
