In this work, we present a review of the GILTT (Generalized Integral Laplace Transform
Technique) solutions for the one and two-dimensional, time-dependent, advection–diffusion …

In this work, we present a new analytical approach for the solution of the advection–diffusion
equation to simulate the pollutant dispersion in the planetary boundary layer. In this method …

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 …

Atmospheric air pollution turbulent fluxes can be assumed to be proportional to the mean
concentration gradient. This assumption, along with the equation of continuity, leads to the …

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 …

A two-dimensional steady-state mathematical model has been developed for the pollutant
released from an elevated source in an inversion layer by parameterizing vertical eddy …

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 mathematical scheme is developed to simulate the vertical turbulent dispersion of air
pollution that is absorbed or deposited to the ground. The scheme is an exact analytical …

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 …
