▪ Abstract Increasing urbanization and concern about sustainability and quality of life issues
have produced considerable interest in flow and dispersion in urban areas. We address this …

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

A three-dimensional computational fluid dynamics model with the renormalization group k–ε
turbulence scheme is developed. The model developed is used to investigate the effects of …

In this study, a detailed model of an urban landscape has been re-constructed inthe wind
tunnel and the flow structure inside and above the urban canopy has beeninvestigated …

Urban turbulence characteristics are investigated at street canyon and neighbourhood
scale. Three high resolution urban large-eddy simulation (LES) studies are performed using …

This is the first paper of a long-term measurement campaign to explore wind, temperature,
radiation and energy fields within an urban canyon. A canyon and a rooftop mast were …

Building roof greening is a successful strategy for improving urban thermal environment. It is
of theoretical interest and practical importance to study the effects of building roof greening …

High concentrations of car-exhaust gases in urban street canyons are typically associated
with low wind velocities or situations when the wind blows perpendicular to the canyon axis …

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 …

The paper presents an overview of the influence of street architecture on the wind and
turbulence patterns in street canyons and discusses the effects on local air quality. The …
