TLDR
In this article, a three-dimensional finite element model for the pollutant dispersion is presented, where the first stage consists on the construction of an adaptive tetrahedral mesh of a rectangular region bounded in its lower part by the terrain and in its upper part by a horizontal plane.About:

On the modeling of atmospheric pollutant dispersion during a diurnal cycle: A finite element study
TL;DR: In this paper, the authors presented a numerical model to study pollutant dispersion in the atmospheric boundary layer (ABL) by accounting for the mechanisms of advection by the mean wind in the horizontal direction, turbulent diffusion in the vertical direction to ground surface, dry deposition, and radioactive decay.

Isogeometric Residual Minimization Method (iGRM) with direction splitting for non-stationary advection–diffusion problems
TL;DR: The method mixes the benefits resulting from isogeometric analysis, implicit dynamics, residual minimization, and alternating direction solver with direction splitting, and shows that the resulting system of linear equations has a Kronecker product structure, which results in a linear computational cost of the direct solver.

A multimesh adaptive scheme for air quality modeling with the finite element method
TL;DR: In this paper, a multimesh adaptive scheme for convection-diffusion-reaction problems for a large number of components is presented, where the evaluation of the nonreactive part for each component and the reaction at each node constitute independent tasks.

A comparison of the trajectories of rising buoyant plumes with theoretical/empirical models
TL;DR: In this article, the trajectory of a plume of hot gas from a power station is shown to be well represented by the equation z = AQ 0.25 x ∗0.75 U where z is the rise above the source (m), Q is the rate of heat emission ( MW ), U is the wind speed at 1.5 stack heights (m s −1 ) and x ∆ (m) is a function of the distance downwind, atmospheric stability and stack height, x ∐ is approximately equal to the distance up to a few hundred metres and approaches an

Experimental determination and analysis of CO2, SO2 and NOx emission factors in Iran's thermal power plants
TL;DR: In this article, the emission factors of CO2, SO2 and NOx emitted from Iran's thermal power plants are fully covered in this paper, and the results show that flue gases emitted from these power plants will experience an intensive decline if renewable, hydroelectric and nuclear types of energy are more used, power plants efficiency is increased and continuous emission monitoring systems and power plant pollution reduction systems are utilized.
