“…For investigation of the air distribution in aircraft cabins, laboratory tests have been carried out in small cabin mock‐ups to characterize the jets along the diffusers, the main flow in the cabin, thermal plumes from heated manikins, and gasper‐induced flow . At the same time, efforts have been made to evaluate contaminant transport in cabins.…”

Ventilation systems for commercial airliner cabins are important in reducing contaminant transport and maintaining thermal comfort. To evaluate the performance of a personalized displacement ventilation system, a conventional displacement ventilation system, and a mixing ventilation system, this study first used the Wells-Riley equation integrated with CFD to obtain the SARS quanta value based on a specific SARS outbreak on a flight. This investigation then compared the three ventilation systems in a seven-row section of a fully occupied, economy-class cabin in Boeing 737 and Boeing 767 airplanes. The SARS quanta generation rate obtained for the index patient could be used in future studies. For all the assumed source locations, the passengers' infection risk by air in the two planes was the highest with the mixing ventilation system, while the conventional displacement ventilation system produced the lowest risk. The personalized ventilation system performed the best in maintaining cabin thermal comfort and can also reduce the infection risk. This system is recommended for airplane cabins.

“…The characteristics of airflows and particle distributions in airliner cabins are usually determined by experimental measurements [ [31] , [32] , [33] , [34] ] and numerical simulations [ [35] , [36] , [37] , [38] ]. The air distribution affects the distribution of particles and spread of pathogenic microbial aerosol particles [ 39 , 40 ].…”

“…The detailed geometry boundary conditions can be found in previous studies. 21,[24][25][26] Figure 1(b) shows the air conditioning system of the cabin mockup and thermostatic chamber under mixing ventilation. Two air condition systems were designed to control the air and surface temperature in the cabin mockup and thermostatic chamber.…”

Aircraft cabin mockup has been accepted as a benchmark tool to study the aircraft cabin environment. Some researchers used computational fluid dynamics to predict the cabin environment, but the model always needs to be validated by accurate and comprehensive experimental data obtained from the cabin mockup. This study measured thermo-fluid boundary conditions, airflow and temperature distributions by appropriate instruments in a full-scale seven-row aircraft cabin mockup. We used an improved interpolation method to obtain the airflow and temperature distributions. For airflow fields, the interpolation regions were determined based on the sampling location. For the temperature field, in addition to sampling locations, cabin wall temperatures were also needed to be set as interpolation boundary. Non-uniformity coefficient was applied to evaluate homogeneities of air supply velocities and zonal wall temperatures. The measurement error and uncertainty were quantified in detail to evaluate measurement accuracy. We found that the uncertainty of the air supply velocity measured by hot-sphere anemometers was lower than that of airflow field velocity measured by ultrasonic anemometers.
