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

Computational fluid dynamics (CFD) models have been used for the simulation of urban
airflow and pollutant dispersion, due to their capability to capture different length scales and …

Air pollution and heat stress are major concerns associated with the liveability, resilience
and sustainability of cities. They directly affect health and comfort and are associated with …

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 …

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 …

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 …

This cross-cultural research is an inaugural attempt to investigate the outdoor thermal
comfort and the effect of cultural and social differences in hot arid climates. Case studies …

Large-eddy simulation (LES) is used to systematically analyse the impacts of trees on air
quality in idealised street canyons. The LES tree model includes radiation, transpiration …

Proper ventilation of urban streets is important for safeguarding the health and comfort of
urban inhabitants. To compare the influence of different street canyon building geometries …

Accurate models of turbulent wind fields have become increasingly important in the
atmospheric sciences, eg, for the determination of spatiotemporal correlations in wind parks …
