Effects of building wall arrangements on wind-induced ventilation through the refuge floor of a tall building
Cheng, C. , Lam, K. M. , & Demirbilek, Nur (2008) Effects of building wall arrangements on wind-induced ventilation through the refuge floor of a tall building. Journal of Wind Engineering and Industrial Aerodynamics, 96(5), pp. 656-664.
Wind-induced natural ventilation plays an important role in the fire and smoke safety of a refuge floor. This paper reports a computational fluid dynamics study to investigate the effect of building wall arrangements on the amount of wind-induced ventilation through a refuge floor which is located at the building mid-height. The refuge floor analysed has a large service core at its centre and is surrounded by exterior building walls, which are arranged in nine configurations that represent varying degrees of opening to wind flow. Results of computed flow patterns show that the wind-induced natural ventilation rate of a refuge floor varies significantly depending on the number of enclosing external walls and the incidence wind angle. A refuge floor, having only one side open, results in the worst natural ventilation and is not recommended.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
