Abstract

Re-entrant area is a common feature in Hong Kong's residential buildings. It is a semi-open light well to provide lighting and ventilation for the immediately adjacent spaces. Since there is a lack of guideline and regulation for re-entrant area design, deep re-entrant areas are often seen in Hong Kong. The physical shape of which, similar to a deep vertical trap, appears to create ventilation problems. This research reviewed the current design of re-entrant area studying the ventilation within re-entrant area using Computational Fluid Dynamics. The study focused on I-shaped re-entrant area, which is the commonest in Hong Kong's cruci-form apartment buildings. Five variations of the configurations, such as different widths, depths and heights, were studied. By examining the flow field and air change rate at the interfaces of the re-entrant area, the causes of the ventilation problems and the key method to improve the ventilation within re-entrant area were identified.
