Wind has been utilized for passive ventilation and mechanical power since antiquity. As an
abundant renewable resource, today, wind is increasingly seen as a critical resource to help …

Idealized pollutant sources are widely used by the scientific community to replicate traffic
emissions in wind tunnel tests and CFD simulations. However, it is unclear to what extent …

Congested urban forms deteriorate urban ventilation, causing the problem of poor wind
comfort at the pedestrian level. Pocket parks are small-scale open spaces for …

The application of cool materials in cities inevitably has an impact on the urban
microclimate, but there is a lack of such studies. Therefore, this study investigated the effects …

Road side shapes, including balconies, have great impacts on airflow around buildings, but
the couple-effect of the balcony structure and wind direction on the canyon ventilation has …

Climate change is expected to exacerbate urban microclimatic conditions and have adverse
effects on human morbidity and mortality. However, there is limited knowledge on the impact …

In urban street canyons, wind and vehicle motions jointly influence the pollutant dispersion.
The present study systematically investigated the impact of (i) traffic direction,(ii) traffic …

The deterioration of the urban environment has captured the attention of governmental
departments and research institutions, which aim to improve the urban environment from the …

Rising urban temperatures, noise and air pollution, and the loss of biodiversity are pressing
problems in cities worldwide that call for action at different scales to improve the livability of …

This study conducted large-eddy simulations (LES) on the pollutant reduction effects of
hedge and solid barriers in a three-dimensional idealized street canyon with an aspect ratio …
