Abstract

To investigate the impact of opening factors on the ventilation of enclosed buildings, numerical simulations were conducted to analyze the coupling airflow between upwind and downwind buildings. The study focused on the effects of window opening percentages (5%, 7.5%, 10%, 12.5%, and 15%) and the height of window opening floors (4 floors) on the indoor environment. The results show that when windows are opened on different floors, the window opening floor height (WOFH) of the upwind building has little influence on the downwind building, and similarly, the WOFH of the latter does not significantly affect the former. However, as windows are opened on the same floor with the same window opening percentage (WOP), the indoor ventilation rate of the upwind building increases with the increase of the WOFHs, but decreases slightly on the top floor (4th floor). In contrast, the indoor ventilation rate of the downwind building is not affected. Both upwind and downwind buildings experience an increase in ventilation rate with the increase of WOPs. Additionally, the ventilation rates of upwind and downwind buildings are linearly correlated with the ventilation ratios approaching 2. The findings of this study could provide a solid foundation for further study of the dispersion of pollutants in enclosed buildings.
