This study investigates the impacts of tree-planting pattern and tree trunk height on the flow
structure and pollutant dispersion inside a street canyon using the numerical model …

Vehicle interior air quality (VIAQ) was investigated inside 14 diesel/non-diesel taxi pairs
operating simultaneously and under normal working conditions over six weekday hours …

This paper investigates the influence of viaduct, noise barrier, and the ratio of leeward and
windward building height (H1/H2) on flow regime and particulate matters (PM) dispersion in …

The use of fossil fuels in traffic is a significant source of air pollutants and greenhouse gases
in rapidly growing and densely populated cities. Diesel exhaust emissions including particle …

Pollutants in tailpipe emissions can be highly elevated around roadways, and in early
mornings the pollution plume can extend hundreds of meters into surrounding …

Particle number size distributions have been measured simultaneously by scanning mobility
particle sizers (SMPSs) at five sites in central London for a 1 month campaign in January …

Urban pedestrian-level air quality is a result of an interplay between turbulent dispersion
conditions, background concentrations, and heterogeneous local emissions of air pollutants …

Computational fluid dynamics simulations were performed to investigate flow and pollutant
dispersion in a 2D street canyon of aspect ratio H/W= 1. Different from other works, the …
