Urban street canyon flows play a central role in microclimate control, from street canyon to
neighbourhood and city scale, which affect pollutant dispersion, thermal comfort of residents …

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

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 …

This paper reviews the state of knowledge on modelling air flow and concentration fields at
road intersections. The first part covers the available literature from the past two decades on …

Air pollution in cities, intensified by vehicular traffic emissions and reduced ventilation, poses
a significant health risk. Obstacles, like solid or vegetation barriers, are being considered as …

Street intersections play an important role in determining pollutant concentrations in the
urban canopy–vehicle emissions often increase in the vicinity of road intersections, and the …

Operational models for pollutant dispersion in urban areas require an estimate of the
turbulent transfer between the street canyons and the overlying atmospheric flow. To date …

The prediction of the probability density function (PDF) of a pollutant concentration within
atmospheric flows is of primary importance in estimating the hazard related to accidental …

Understanding the dynamics of mass exchange between a street canyon and the overlying
atmosphere is crucial to predict air quality in urban areas. Despite the large number of …

Atmospheric surface layer (ASL) consists of the inertial sublayer (ISL) and the roughness
sublayer (RSL) with different dynamics. This study characterizes the ASL flows over real …
