A study of natural ventilation in a refuge floor

This paper reports a study based on CFD simulations of refuge floor natural ventilation induced by wind flow around a high-rise building. The simulations are validated by wind tunnel measurements. The results reveal that at all wind angles, the wind can enter the refuge space from the windward side and escape from the leeward side. At some wind angles, the wind is found to re-enter the refuge space. Based on those results, suggestions are made by the authors.
