Abstract

Abstract: To understand contaminant transmission mechanism well and control and reduce the contaminant within the aircraft cabin, the influence of different air supply modes on the contaminant transmission characteristics and air quality within the aircraft cabin is investigated. A five-row cabin model for a Boeing 737-200 is established by the CFD technology, and the airflow field and contaminant concentration field within the cabin are calculated when two air supply modes are adopted:air supply via ceiling, and air supply via ceiling and wall sides. Experiments are performed in the cabin mockup to validate the calculation results. The air quality is evaluated by air age, which is used as an evaluation index. The results indicate that the air supply mode via ceiling and wall sides is more conductive to contaminant transmission, and the ventilation is more sufficient; while the air supply mode via ceiling is more likely to cause a high contaminant concentration around the contaminant source, the ventilation is poor, and the cost is high.

Key words: cabin environment, air quality, airflow field, contaminant, transmission law, air age
