Computational fluid dynamics (CFD) modelling is a powerful tool for assessing air ventilation in urban street canyons. These street canyons are flanked by tall buildings on either side of a street, which would degrade pedestrian-level winds and air quality due to weakened airflows and turbulence. CFD modelling facilitates the simulation of airflows and the identification of areas with poor ventilation. It also offers systematic sensitivity tests to various building configurations to refine urban planning and design decisions, promoting public health and city sustainability.
In the seminar, the speaker will introduce the application of CFD modelling for analyzing and studying air ventilation patterns in urban environments, as well as how CFD can help urban planning design. Moreover, he would share his experience on how CFD can inform the design of building configurations to optimize pedestrian-level ventilation and pollutant removals in urban areas.

Speaker: Dr Chun-Ho LIU, Department of Mechanical Engineering, The University of Hong Kong.
Dr Chun-Ho LIU has received his BEng and PhD degrees from the Department of Mechanical Engineering, the University of Hong Kong (HKU). He joined HKU in 2007 where he is currently Associate Professor, teaching courses in air quality, thermofluid and numerical methods. His research areas are:
1.
Air pollution physics and chemistry;
2.
Geophysical turbulence; and
3.
Scientific computing.
Dr Liu uses large-scale computer models to examine atmospheric turbulence and its effect on air quality. In view of the dense built environment in Hong Kong, his current focus is urban atmospheric boundary layer (ABL). He was one of the pioneers, using computational fluid dynamics (CFD), to diagnose the flows and pollutant transport in street canyons.
