In the last two decades, Computational Fluid Dynamics (CFD) has shown great potential as
a powerful and cost-efficient tool to troubleshoot existing disinfection contactors and improve …

Wind comfort and wind safety for pedestrians are important requirements in urban areas.
Many city authorities request studies of pedestrian wind comfort and wind safety for new …

Computational Fluid Dynamics (CFD) is increasingly used to study a wide variety of complex
Environmental Fluid Mechanics (EFM) processes, such as water flow and turbulent mixing of …

Monitoring street-level particulates is essential to air quality management but challenging in
high-density Hong Kong due to limitations in local monitoring network and the complexities …

This paper reviews the application of CFD for designing and parametric studies of wind-
induced natural ventilation. The approaches employed in such applications of CFD are …

Due to the continuous urban development, it becomes necessary to investigate the complex
aerodynamic interactions within the built environment. These interactions lead to a …

Urban compact buildings impose large frictional drag on boundary-layer air flow and create
stagnant air within the building environment. It results in exacerbating the street-level …

Abstracts Compared with the traditional method of detrended fluctuation analysis, which is
used to characterize fractal scaling properties and long-range correlations, this research …

Mobile and ubiquitous sensing of urban air quality (AQ) has received increased attention as
an economically and operationally viable means to survey atmospheric environment with …

We applied data-based recurrence CFD (rCFD) to model pollutant dispersion in near-field
flow configurations. In case of complex topologies, the global-domain version of rCFD fails to …
