Abstract

The quality of Indoor and outdoor air have a significant impact on the health and well-being of the general population. The recent trend toward urban living and the dramatic increase in high-rise residential building construction to meet this growing demand heighten our awareness of the impact of high-density high-rise building development on air ventilation and dispersion of air-borne pollutants. Evidently building arrays in close proximity and deep street canyons adversely affect pedestrian level air circulation, air ventilation within the urban fabric, and dispersion of air pollutants. This seminar presents the results of investigations on air ventilation and air pollutant dispersion around high-rise buildings using wind tunnel model studies and CFD simulations. The results show that air ventilation and air pollutant dispersion around buildings are dominated by wind-structure interaction, with building shape, building grouping and separation, and podium structure also playing a significant role.

報告人簡介

Professor Kenny Kwok is currently a Professor of Engineering at The University of Sydney. He was previously Professor of Engineering at Western Sydney University (2008 to 2017), Professor of Civil Engineering at Hong Kong University of Science and Technology (1998-2008) and Professor of Wind Engineering at The University of Sydney (1999-2002). His research interests include wind engineering, structural dynamics, vibration control, human perception of motion, and environmental fluid mechanics, particularly with respect to the dynamic behaviour of tall buildings and flexible structures in strong winds. His research focuses on fundamental aspects of building aerodynamics and wind-structure-occupant-damper interactions, and their practical applications in real life situations. He has published over 500 articles in journals, book chapters, invited and keynote papers, and conference papers. He is the recipient of 2019 ASCE Jack E. Cermak Medal, 2019 International Association for Wind Engineering Senior Award and Davenport Medal, a Life Member of the Australasian Wind Engineering Society, and a Fellow of the Hong Kong Institution of Engineers and Institution of Engineers, Australia.
