Fine particle dispersion in a commercial aircraft cabin
The spread of particles or contaminants in aircraft cabins is of interest due to the large number of passengers and their close proximity to each other. This close proximity causes concern about the spread of disease and contaminants among passengers. To understand the aircraft cabin environment and the dispersion of fine particles, an experimental study was conducted in an 11-row wide-body aircraft cabin mockup. The experiment focused on the longitudinal dispersion of particles throughout the cabin. The data show the regions close to the source experience higher levels of exposure and higher levels of variation, while locations farther from the source show lower exposure levels and less variation. The variations close to the source likely stem from the interaction of the quick injection burst of particles with chaotic airflow. Particles release in the second row were detected at all locations in the cabin mockup, but there was roughly a 37% decrease in concentration with each successive row in the longitudinal direction from the release location.
