A simulation study of ventilation and indoor gaseous pollutant transport under different window/door opening behaviors

The window/door opening behavior of occupants is a very important factor in determining the airflows and ventilation conditions in buildings, on which indoor pollutant concentration and transport are highly dependent. A two-room residence model was simulated in this study to analyze the airflow characteristics and pollutant transport under different window/door opening behaviors. Airflows were unidirectional and the residence could not be treated as a well-mixed zone when there were no temperature differences. If there were temperature differences, two-way airflow occurred at the exterior window of the room when it was open and the interior door was closed, resulting in a much larger ventilation rate than the situation without temperature differences. Strong two-way airflow occurred at the interior door in the case of the exterior window closed and interior door open, as the air in the two connected rooms was well mixed after the interior door was opened for tens of minutes. The ventilation rate of the room with double-sided ventilation was much higher than that of the room with single-sided ventilation, even though the total opening areas were the same. Opening the exterior window and closing the interior door could effectively remove pollutants from a polluted room and prevent their transport to a clean room. Field experiments were performed and the main conclusions of the simulation were verified.

Large-eddy simulation of the containment failure in isolation rooms with a sliding door—An experimental and modelling study

In hospital isolation rooms, door operation can lead to containment failures and airborne pathogen dispersal into the surrounding spaces. Sliding doors can reduce the containment failure arising from the door motion induced airflows, as compared to the hinged doors that are typically used in healthcare facilities. Such airflow leakage can be measured quantitatively using tracer gas techniques, but detailed observation of the turbulent flow features is very difficult. However, a comprehensive understanding of these flows is important when designing doors to further reduce such containment failures. Experiments and Computational Fluid Dynamics (CFD) modelling, by using Large-Eddy Simulation (LES) flow solver, were used to study airflow patterns in a full-scale mock-up, consisting of a sliding door separating two identical rooms (i.e. one isolation room attached to an antechamber). A single sliding door open/ hold-open/ closing cycle was studied. Additional variables included human passage through the doorway and imposing a temperature difference between the two rooms. The general structures of computationally-simulated flow features were validated by comparing the results to smoke visualizations of identical full-scale experimental set-ups. It was found that without passage the air volume leakage across the doorway was first dominated by vortex shedding in the wake of the door, but during a prolonged hold-open period a possible temperature difference soon became the predominant driving force. Passage generates a short and powerful pulse of leakage flow rate even if the walker stops to wait for the door to open.
