Local mass transfer coefficients over idealised two–dimensional urban street canyons
In view of the large number of urban inhabitants, ventilation and pollutant transport in urban areas are major research problems for several decades. This paper focuses on the studies of the correlation between the ventilation and pollutant removal over idealised two–dimensional urban street canyons using wind tunnel experiments in the Department of Mechanical Engineering, The University of Hong ...

Gaseous pollutant dispersion around urban-canopy elements: wind tunnel case studies
There is an evident lack of reliable and detailed in situ measurement data for verifying numerical predictions of atmospheric dispersion in the urban environment on sub-meso scales. Wind-tunnel studies of dispersion around typical elements of the urban canopy (isolated buildings, groups of buildings, street canyons) could provide valuable substitutes for field datasets. They can achieve a high ...
