Near-field pollutant dispersion in the urban environment involves the interaction of a plume
and the flow field perturbed by building obstacles. In the past two decades, micro-scale …

This article deals with the state-of-the-art of experimental and numerical studies carried out
regarding air pollutant dispersion in urban environments. Since the simulation of the …

Over the last 50 years the large-eddy simulation (LES) technique has developed into one of
the most prominent numerical tools used to study transport processes in the atmospheric …

Prediction accuracy of pollutant dispersion within an urban street canyon of width to height
ratio W/H= 1 is examined using two steady-state Reynolds-averaged Navier–Stokes (RANS) …

Global urbanization has underscored the significance of urban microclimates for human
comfort, health, and building/urban energy efficiency. However, analyzing urban …

In the last two decades substantial advances have been made in the understanding of the
scientific basis of urban climates. These are reviewed here with attention to sustainability of …

In order to control and manage urban air quality, public authorities require an integrated
approach that incorporates direct measurements and modelling of mean pollutant …

Abstract uDALES is an open-source multi-physics microscale urban modelling tool, capable
of performing large-eddy simulation (LES) of urban airflow, heat transfer, and pollutant …

This work develops a data analysis procedure, namely, proper orthogonal decomposition
(POD)-dynamic mode decomposition (DMD) augmented analysis, to isolate the energy-and …

Air pollutants emitted from vehicles in street canyons may be reactive, undergoing mixing
and chemical processing before escaping into the overlying atmosphere. The deterioration …
