Recent studies indicate the necessity of addressing traffic-related air pollution in urban
environments, as street canyons are known for their lack of natural ventilation and increased …

Abstract Purpose of Review The air quality management within urban street canyons can be
improved by enhancing ventilation for dispersion of pollutants. The purpose of this review is …

This study investigates the effect of roof and façade geometry on the mean wind flow and
turbulence in street canyons, as well as the ability of numerical simulation techniques in …

As the technology of small aircraft systems continues to improve and the number of their
possible applications grows, they are likely to be used more frequently in urban …

Vertical transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)
along a vertical column of flats has been documented in several outbreaks of coronavirus …

Urban climate models can predict the environmental impacts of urban development by
simulating the exchange processes between the atmosphere and urban surfaces. A …

The Reynolds number for flow in a street canyon, Re= U ref H/ν (where U ref is a reference
velocity, H the street canyon height, and ν the kinematic viscosity), cannot be matched …

Increasing urbanization, evolving urban landscapes, and growing populations require an
accurate representation of urban areas and urban processes at microscale, regional, and …

The aim of this work is to analyse the formation mechanisms of large-scale coherent
structures in the flow around a wall-mounted square cylinder, due to their impact on pollutant …

Flow regimes occurring in urban canyons are strongly influenced by the geometrical shape
of the buildings; however, fluid dynamic investigations are typically carried out using …
