An analytical model is presented for assessing the coupled processes that govern water flow
and volatile organic compound (VOC) transport from the saturated zone through the vadose …

Abstract Large Eddy Simulation (LES) spectral data and Taylor statistical diffusion theory are
used to obtain Eddy diffusivities in a convective boundary layer. The derivation employs a …

We present a semi-analytical model for the dispersion of passive scalars from continuous
ground sources up to distances of a few hundred metres. We attempt to cope with problems …

In the literature there exists a variety of pollution of dispersion models and in general,
Gaussian models are used worldwide by environmental agencies in regulatory applications …

O objetivo deste trabalho é propor uma nova formulação para o tempo de descorrelação
Lagrangeano em função da distância da fonte para uma turbulência não homogênea na …

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 …

The atmospheric boundary layer (ABL) is the lowest layer of the atmosphere unique in its
interactions with the surface, which makes for complex mixing and transfer of heat, moisture …

Existe uma variedade de modelos de dispersão de poluentes, em geral, os modelos
gaussianos são usados em todo o mundo por agências ambientais com intuito de …

According to the fact that, in comparison with the other spirometers, a flow-based spirometer
benefits from a wide range of advantages such as being easy to use and calibrate, in this …

Questões ambientais estão no centro das discussões nas últimas décadas. A poluição
atmosférica, causada pela expansão pós-revolução industrial fez surgir a necessidade de …
